Most library users think of reference sources, books, and periodicals as their main "go to" information sources for library research. However, many important research findings are published first and only as technical notes, conference proceedings, electronic communications, projects reports, and other lesser-known works. Traditional finding aids may not be effective in locating and accessing these materials. These types of documents are known as "grey literature" or "gray literature".
Although Google is getting better at identifying grey documents, these information sources continue to be part of the "hidden web" or "deep web". In other words, they're not easy to find. They often lie deep inside web servers without metadata or other descriptions important for identification by web crawlers.
Grey Literature Defined
Grey literature includes materials not formally published through traditional commercial publishing channels. Many of these works are found on websites. According to (Reitz, 2014), grey or gray literature is
"documentary material in print and electronic formats, such as reports, preprints, internal documents (memoranda, newsletters, market surveys, etc.), theses and dissertations, conference proceedings, technical specifications and standards, trade literature, etc., not readily available through regular market channels because it was never commercially published/listed or was not widely distributed. Such works pose challenges to libraries in identification (indexing is often limited) and acquisition (availability may be uncertain). Absence of editorial control also raises questions of authenticity and reliability. Alternative methods of supply and bibliographic control have evolved in response to the need to preserve and provide access to such material."
According to Farace and Schopfel (2010), the term grey literature generally includes three types of documents: conference proceedings, reports, and doctoral theses. The definition usually limits grey literature to those documents that lack “commercial control”. In other words, they aren’t published through traditional publishing houses in books or journals. Commercial literature is sometimes referred to as “white literature”.
Unpublished manuscripts, newsletters, patents, technical notes, field notes, product catalogs, presentation materials, correspondence, laboratory notes, and data sets may also be included under the umbrella of grey literature. Farace and Schopfel (2010) note that these documents can contain “unique and significant” information that isn’t published elsewhere.
Institutions of higher education are major producers of grey literature. From online course materials to dissertations, universities churn out endless content across disciplines.
Read Schopfel, Joachim & Farace, Dominic, J. (2009). Grey literature. Encyclopedia of Library and Information Sciences, 3rd Edition. Taylor and Francis.
GreyNet is "dedicated to research, publication, open access, and education in the field of grey literature. This website is useful for collecting background information about this topic.
Pros and Cons of Grey Literature
Grey literature can provide useful information on a topic. Because it doesn't go through traditional publication channels, it can be shared very quickly. Grey literature often summarizes and communicates ideas in ways that are different from other documents. Many of the documents are concise, so these sources can convey complex information in simple terms, quickly. Many companies and agencies produce grey literature such as brochures and pamphlets for public distribution, so these works are a good gauge of public interests.
Besides the ability to identify additional information on a topic, grey literature provides the opportunity to locate materials with alternative perspectives and lesser known specializations. These types of information sources can also be used to battle against publication bias. In other words, publishers tend to select high-impact studies with positive results for publication. This means that many excellent studies go unnoticed by the mainstream. Non-traditional publishing outlets provide an opportunity for this research to be read.
On the other hand, it's important to remember that many pieces of grey literature have not been peer reviewed. As such, it's essential that scholars carefully review the sources themselves. In addition, it can be difficult to locate studies of interest. Unlike subscription databases that provide well-indexed materials, some open access tools have limited search capabilities.
According to AcademyHealth (2006),
"grey literature has long-term value, particularly because it provides policy context and implications that may not be found in the published literature. In fact, advisory committee members believed that the value of grey literature is on par with that of traditional published literature. Relevancy, progress, and how debate changes over time on a particular topic can be assessed from these materials. Another use of grey literature is to establish historical documentation. The progress of a document to its finished form can sometimes be as valuable as the finished product, and the various drafts of a document can fill in gaps in the historical record."
Access to Grey Literature
Interest in grey literature has gone hand-in-hand with the recent open access movement. Many librarians and subject matter researchers began to realize that a huge untapped resource needed to be made widely available. Rather than going to publishers, many librarians and scholars worked together to develop their own databases and institutional repositories to house these important data collections. The government has also gotten on board to promote open access to documents.
In the past, it was often difficult to access dissertations, theses, reports, and other types of print materials. However, universities, government agencies, and other organizations are increasingly digitizing these materials and making them available online. The search is on for more documents that can be shared.
Look for grey literature in the following locations:
- Discipline-specific Subscription Databases. Many large databases provide the option to search by a particular document type. Others provide a list of categories that include different document types.
- Open-Access Databases. Increasingly, documents are being made available at open-access database websites. These websites often serve a particular discipline.
- Institutional Repositories. Many institutions are making grey literature produced by their organization available to the public. When looking for grey literature in a particular discipline, seek out well-respected universities who specialize in that area.
- Organization Websites. Nonprofits as well as many businesses provide quality information to the public. Examine the navigation for the organization's website looking for menu options such as publications, reports or documents. Seek out the website's site map to see if links are provided. Do a site search for a document type such as conference proceedings. If the website doesn't provide a good search tool, use Google. Search site:doctorswithoutborders.org reports.
Go on a grey literature scavenger hunt. Select a topic and search the major databases services such as EBSCO, Gale, and ProQuest seeking out documents. Next, visit an organizational website related to your topic. Look for reports, proceedings, or other types of grey documents.
Let's explore the many types of documents in the category of grey literatures.
From conference papers and posters to conference programs and proceedings, products of conferences are an important source of information for researchers. They often contain the latest information on a topic and may be the only place that an unpublished work can be located. Conference documents are often available through conference websites and are archived from year-to-year by the sponsoring organization. In some cases, the proceedings are only available to those that attended the conference.
- Call for papers - a document seeking scholars who wish to submit a paper for consideration at a conference.
- Conference papers - a paper presented at an academic conference that may or may not be part of a conference proceedings.
- Conference posters - a visual presented at an academic conference.
- Conference proceedings - a collection of academic papers associated with an academic conference representing the contributions of presenters at the meeting.
- Conference programs - a booklet containing information about a conference often including the schedule of event; details about presentations such as location, description, and categories; list of exhibitors; and index to presenters and presentations.
Do a search in ProQuest for conference proceedings and papers.
PapersFirst via FirstSearch is available through WorldCat. You can search both PapersFirst and Proceedings using the Databases option.
Lamb's Personal Connection
In many subject areas, library users will want the most up-to-date information. Conferences are one of the best sources for information.
Go to an organization's website and look for their latest conference. The website will often note where the papers can be located. Many times organization websites archive these materials themselves and they may not be available anywhere else.
If you aren't able to locate the most recent conference proceedings, there are other ways to connect with new content. Scan through online conference programs for the names of key researchers. Then, search for recent articles by those people. You may also be able to locate articles at pre-print websites.
From syllabi and calendars to course guides and tutorials, many course materials are not formally published. Many of these materials reside on university web-servers. While some are behind firewalls, others are open access. Use of content management systems such as Blackboard and Canvas has increased online availability of course materials.
Some universities such as MIT have embraced the open courseware concept.
Go to MIT Open Courseware. Search for a course in your discipline area using the Course Finder. Notice that many of the syllabi include resource lists. These can be valuable sources of information.
Data Sets and Statistics
From voting patterns to animal populations, statistical information is critical across disciplines. Keep in mind that most scholars will want the original source of data rather than a source that simply converted the data into a chart or graphic. Statistical sources provide rankings, ratings, and raw data on a wide range of topics.
Regardless of your discipline, it’s important to be familiar with key concepts related to data and statistics.
Data and Statistics Defined
Data and statistics are different.
Julia Bauder (2014, 3) states that data
"is raw input for some sort of statistical analysis. A list of all of the traffic accidents in New Jersey in 2010, with information about the drivers (e.g., age, blood alcohol content, whether they were using a cell phone at the time of the accident) and the accident (e.g., time of day, weather, number of cars involved) would be data."
Bauder also (2014, 3) states that statistics
"are the results of a statistical analysis of the data. Statistical analysis does not have to mean some sort of complicated multivariate regression. In many cases, it is simply an average, a percentage, or a frequency. For example, the percentage of accidents that occur during snowstorms, or the frequency of accidents involving teenage drivers, are examples of statistics that could be generated from this data."
Finally, Bauder notes that "certain pieces of information can be treated as either statistics or data, depending on what the user wants to do with that information." For instance, you might use a statistic such as the unemployment rate in a research paper. However, this single number could be joined with other numbers for an analysis of changing unemployment rates. In this case, that single number would be treated as a data point (Bauder, 2014).
Rather than studying the entire population, researchers often collect data from a sample that represents the larger population. Sampling is based on the idea that you can make generalizations from a representative group.
Descriptive statistics involve the use of numerical and graphical representations of data to seek out patterns and draw conclusions. Inferential statistics use sample data to make predictions about larger sets of data.
In many cases data is used to forecast, project, or estimate. In other words, data is used to predict what might happen in the future. Keep in mind that many factors such as technological advances or natural disasters can interfere with projections.
A data set is a collection of data. This data may be presented on a single table or matrix. However, it may also be contained in a large database and displayed in various forms. Examples include:
- Census data
- Demographic information
- Results of polls, questionnaires, and surveys
- Satellite data
- Statistical surveys
According to Bauder (2014, 4), microdata is
"used to refer specifically to the kind of data that is, unequivocally, data rather than statistics: raw observations, survey responses, and the like that are not the product of any kind of statistical analysis or summary."
According to Bauder (2014, 4), aggregate data is
"data produced by some sort of statistical procedure, such as averaging or, in the most basic and perhaps the most common example, simply adding up the number of cases. Monthly unemployment rates are an example of what might be referred to as aggregate data".
Data and Statistics in the Library
Today's Internet allows users to quickly download large amounts of information. In addition, tools like Microsoft Excel allow anyone make use of this information. Kellam and Peter (2011) have found that there's increasing interest in quantitative information. Users without a background in statistics can search data sets that provide an easy-to-use interface such as American Factfinder. However complex data set that don't provide an interface can be useless without specific software and analysis skills. Kellam and Peter (2011, 15-17) state:
- In most cases, researchers must use a statistical software package such as SAS or SPSS to analyze these data set.
- In many cases, a researcher may need to use a codebook or a data dictionary to analyze the data.
- Microdata may be available either as a confidential or as public-use files.
Librarians working with data need to think about what's possible and practical with information seekers.
"Aggregate statistical sources can be a gateway into more complex data for novice users; librarians need to be aware of and learn how to support these basic numeric products with skill. Librarians can encourage interest in using numeric information during the early stages of student research. For example, we should encourage lower-level students to use sources like American Factfinder" (Kellam & Peter, 2011, 19).
Most university faculty have access to software such as SAS or SPSS. However for library users without these tools, open source alternative such as The R Project can be useful for statistical computing and graphics.
General Sources of Data and Statistics
Gathering data and statistics is a time-consuming and often expensive process. Governments around the world collect public data as well as global organizations such as the United Nations. In addition, private data is gathered by businesses, nonprofits, and other types of organizations for a variety of purposes. This information may or may not be available to the public.
Sources of data include
- American Factfinder
- Data.gov - a starting point for US data.
- Datahub - a free, data management platform from Open Knowledge Foundation.
- Eurostat - European Statistics
- Research Pipeline - a wiki with links to a wide range of science and social data resources.
- State of Working America
- Statistical Abstract of the United States
- UK Government Data - a starting point for UK data.
- World DataBank
Dissertations and Theses
Theses and dissertations are often produced by graduate students as part of their master's or doctoral studies. These works are often used by others in research. According to Juznic (2010, 39), “a thesis is a written text representing the independent research and authorship of a single individual.” Juznic notes that this document is produced to demonstrate that a graduate has subject-matter knowledge in their discipline and is capable of independent research. The structure of a thesis is similar around the world regardless of discipline.
Increasingly, Electronic Thesis and Dissertations (ETD)s are being produced, archived, and circulated. The term ETD refers to “a thesis or dissertation that is archived and circulated electronically rather than archived and circulated in print” (Juznic, 2010, 41). They generally take the form of word processing documents or Portable Document Format (PDF) files. These electronic files are access through web-based services. Full-text databases of electronic theses and dissertations (ETDs) are now the norm for new documents. In the past, theses were printed and placed in university libraries. In some cases, they were placed on microfilm for distribution.
According to Stock and Paillassard (2010, 118), “next to journal articles and eprints, electronic theses and dissertations (ETDs) are for various reasons the most frequent document type found in open archives.” They stress that the rules for defining and referencing these documents are well established. In addition, most students are required to deposit their work in an archive or repository to graduate.
Since 1938, University Microfilm International (UMI) in Ann Arbor has collected, abstracted, and indexed doctoral dissertations from both North America and Europe. This service is now electronic, includes more than 90% of dissertations, and is owned by ProQuest UMI Dissertation Publishing.
- Dissertations & Theses Global from ProQuest. This database has an extensive collection of dissertations and theses from around the world, spanning from 1743 to the present day and offering full text for graduate works added since 1997, along with selected full text for works written prior to 1997. It contains a significant amount of new international dissertations and theses both in citations and in full text. Available through IUPUI.
Other major dissertation services also exist.
- NDLTD (Networked Digital Library of Theses and Dissertations) is "an international organization dedicated to promoting the adoption, creation, use, dissemination, and preservation of electronic theses and dissertations (ETDs)."
- SIGLE (System for Information on Grey Literature in Europe) is "a system for information on grey literature in Europe". This group has moved their materials to the OpenGrey Repository.
- WorldCatDissertations via FirstSearch is available through WorldCat. You can search WordCatDissertations using the Databases option.
Today, many of these are digitally-born. In other words, they begin as electronic documents and may not even be available in a print format. Older documents are slowly being added.
Go to Dissertations & Theses Global from ProQuest. Be sure to click the "advanced search" and explore the options. Also try the BROWSE option. Then, browse NDLTD and SIGLE for comparison. Share a 2015 dissertation you find interesting.
Jentery Sayers’s dissertation “How Text Lost Its Source” is an example of the growing number of web-based dissertations. Increasingly, individuals are finding unique ways to share their work.
Citation analysis can be applied to electronic theses and dissertations.

Essays and Treatise
Since early times, scholars have written essays detailing an individual's perspective on a topic. Essays may include criticism, manifestos, arguments, observations, reflections, and many other types of communications. While some essays are published through journals, books, and other formal channels, many others are informally shared as printed documents or web pages.
A treatise is similar in content to an essay, but generally provides more depth. These longer documents are intended to provide the results of investigations, observations, or insights into a subject. Aristotle, Sun Tzu, Euclid, John Locke, David Hume, Thomas Paine, Charles Darwin, Leo Tolstoy, Karl Marx, and others are all known from their treatise.
A wide range of papers fall into the grey literature category. Some examples are listed below.
- Green papers - a tentative government report of policy proposals for discussion and debate. Although it's the first step toward legislation, it provides no commitment to action. These papers often lead to white papers.
- White papers - an authoritative document focusing on a complex issue. This concise paper is a guide to an organization's stand or philosophy on a particular matter.
- Working papers - a document still in draft form used to elicit feedback prior to submission.
When you think of a journal article or report, the final product comes to mind. However in many cases, multiple versions of a document are available. Many of these are considered grey literature because they aren't the final, published version.
- Off-prints are reproductions of an article, chapter, or an excerpt from a paper from a larger publication. It's usually printed at the same time as the original from the same plates of original, but issued separately. They may be given to authors or sold as self contained documents.
- Pre-prints are a version of a document that hasn't been published in a journal. These manuscripts are often in the process of being peer reviewed and are used to receive early feedback from peers.
- Reprints are documents that have already been published and are being printed again or are appearing in a digital version. Reprints have been republished. For example, electronic databases are digital reprints.
Whether working on an internal organization project or addressing the requirements of a grant, project documents can be useful in research.
- Deliverable - a tangible or intangible object generated as a result of a project. Many different types of documents might be generated as project deliverables including progress reports, final reports, and published documents.
- Project Initiation Document (PID) - a contract for a project that details the agreement between the project manager and the project board. It includes the project goals, scope, organization, constraints, and other details.
- Proposal - a document that provides a detailed explanation of a proposed project outlining the entire process. They may be written as part of the dissertation or thesis process, to request grant funding for research, or for other purposes.
- Work Package - a document written as a part of a larger project focusing on a specific aspect of a project.
Research projects often contain their own set of documents. These may include:
- research memoranda
- research notes
- research proposals
- research protocols
- research registers
- research reports
A report is a document that provides relevant information to a specific audience. While the audience may be the general public, reports can also be used internal to an organization.
- Activity report - a report logging the activities of an individual or group.
- Annual report - details the activities of an individual, group, or organization's activities during the preceding year. In some cases these reports are used to share information with a boss, shareholders, or a board. In other cases, they simply serve as a record of activities.
- Committee report - a report written by an individual from a group or the entire group to discuss the committee's processes, procedures, activities, and/or recommendations.
- Country report - provides factual information about a particular country.
- Draft report - a version of a document that is not ready for distribution or publication. Normally, draft reports are circulated so suggestions can be provided for modifications, corrections, and revisions.
- Feasibility report - provides an objective analysis of the potential of a proposed project including the strengths and weaknesses. The document includes investigation, evaluation, research, and conclusions that can be used in making a decision about a project. The document addresses the question of whether the costs are worth the potential value gained. These documents are used as part of market research, to judge environmental impact, and as proof of concept.
- Government report - a document written by individuals working in or with a government agency.
- Internal report - a document not intended to be distributed beyond a particular organization.
- Investigative report - a document detailing an investigation and its results.
- Official report - a document sanctioned by an individual or organization.
- Policy report - a document contains an in-depth analysis of a policy.
- Progress report - describes the status of project activities and achievements along with problems and possible solutions. It normally describes whether objectives are being met and previews the next steps in a project.
- Recommendation report - proposes possible solutions for problems and discusses which are best for particular situations.

From blogs and electronic discussions to email, millions of ephemeral electronic messages are shared every day. These communications can be valuable to researchers.
Marcus Banks (2010) is concerned with the preservation and use of ephemeral grey data such as blog posts and tweets. He notes that findability has also been a problem with grey literature, but the problem is shifting from paper to the need to preserve and access the content on dynamic websites such as social media communications. Examples include
- electronic discussions
- electronic mail
- electronic mailing lists
- social network postings
- video and audio conferences
Lamb's Personal Connection
I teach courses in children's literature. Some of the most useful sources of up-to-date information come from blogs and electronic mailing lists.
For instance, the YALSA-BK list from ALA is a wonderful source of information about what's happening in libraries with young adult literature. For a complete list of ALA mailing lists, go to http://lists.ala.org/.
As a subject matter librarian, there's no way you can LIKE every Facebook page and join every mailing list with the disciplines. However in many cases, it can be useful to search a blog that you keep bookmarked or the archives of mailing lists.
Standards exist in almost every discipline. Library users may seek information about whether there are standards in a particular area and whether they comply with the standards.
A standard is a rule, condition, or guideline for products, processes, or performance.
Organizations and associations create standards related to their profession.
Governments are often responsible for creating and monitoring standards. In the United States, the Standards.gov website is the entry point for identifying standards. The Regulations.gov website is used to seek public opinions regarding proposed regulations.
Many other unpublished works fit into the category of grey materials such as unpublished manuscripts, newsletters, patents, technical notes, field notes, product catalogs, presentation materials, correspondence, and laboratory notes.
- bulletin boards
- case studies
- country profiles
- course materials
- exchange agreements
- fact sheets
- feasibility studies
- journals (i.e., in-house, non-commercial)
- legal documents
- policy documents
- press releases
- product data
- risk analysis
- state of the art
- web pages

Institutional repositories are collections intended to preserve intellectual property of a particular institution or university.
IUPUIScholarWorks is an example.
"IUPUIScholarWorks Repository is a digital service that collects, preserves, and distributes digital material. Repositories are important tools for preserving an organization's legacy; they facilitate digital preservation and scholarly communication. Submissions in digital form include preprints, working papers, theses and dissertations, conference papers, presentations, student capstone projects, faculty-created learning objects, data sets, and more."

Lamb's Personal Connection
I admit to being old. I did my master’s and doctoral work back in the 1980s. My master’s project was typed on an Apple IIe computer and published on a daisy-wheel printer. I submitted my project as a bound volume. Until recently, you had to physically go to the stacks at the Iowa State University Library to read it… like you were going to read it anyway. However, the digitizing team at ISU’s Digital Repository has made it available.

Grey Literature and the Scholarly Publication Cycle
The publication cycle begins with research question, problem, or idea. During the research process, a number of grey documents may be produced including grant proposals, progress reports, technical reports, conference proceedings, and maybe even a dissertation. Next, articles may be written and another round of documents may be produced including green papers, pre-prints, scientific reviews, and others. Finally, journal articles, reprints, books, and other published works may emerge. Finally, others may create documents citing this research leading to another round in the publication cycle. A single research project may generate dozens of documents at various times during the research and publication cycles.
In order to identify the documents generated during the publication, librarians use the searching forward and searching backwards techniques discussed in Bibliometrics section of the course. Let's review this processes now that we have a better understanding of the grey documents that play a role in the process.
Scholars often wonder "does my work matter"? Does anyone read or use my work? Has my work had an impact on my field? Forward searching can address these questions as they related to a particular author and the use of his or her work.
- Begin with a piece of grey literature such as a dissertation, conference paper, or technical report. Create a citation for this document. Use the links on this page to identify a starting document. Keep in mind that this work should be at least a few years old. Ten to twenty year old articles work best. Need help? Do a Google search for LANDMARK or FOUNDATIONAL works in a particular field. You'll find lots of ideas. If you can't find a piece of grey literature you love, it's okay to begin with the author of a journal article.
- Use an Indexing and Abstracting databases, Periodical databases, and other databases to search for the author of this work and seek out journal articles and other publications written by this person on the same or a related topic. Create a bibliography listing citations for each of these works. Use the links on the Periodicals, Databases, and Indexes pages to identify documents. You might also conduct a MetaSearch for this author. Be sure that you've got the correct person.
- Use the Citation Indexes including Web of Science Indexes and Google Scholar to determine whether any of the publications identified in steps 1 and 2 have been cited by others. Then, create a bibliography containing a dozen notable works along with the total number found. Find full-text articles on at least a few of these works. How did the original work contribute to the new work?
- What's your conclusion? Do you think that the author's work has made an impact? If so, how?
Backward searching will allow scholars to trace back to see what articles had an impact on a given work. It's also an interesting way to gain insights into an author and their work.
- Identify a scholar that is well-published in a specific discipline. This person should appear in an journal article devoted to this person, a subject specific biography reference, or Wikipedia. Create a short biographical sketch and list of their works creating formal citations for each item.
- Do an author search in Indexing and Abstracting databases and Periodical databases to locate full-text articles, papers, and books by this person. You may also want to do a Google and Google Scholar search. Select ten works by this author. Analyze the articles. What's the the relationships among these publications? Do they represent different phases of a particular project or different pieces of research? Do the articles follow a particular organizational scheme?
- Analyze and compare the bibliographies or reference lists found at the end of the articles looking for patterns. Are the publications listed through self-citations (i.e., the author citing him/herself)? Does this person cite the same people? Are the people cited connected to the author in some way (e.g., same university, same publication, same co-author)?
- What's your conclusion? Looking back over this author's body of work, can you find patterns? Can you identify particular people or lines of thought that influenced this person's work?
Lamb's Personal Connection
One of my favorite examples of forward citation chasing is the landmark article, What is the History of Books by Robert Darnton. It serves as the basis for my History of the Book course. A search in Google Scholar finds that this article has been cited 525 times. Actually, his book The Great Cat Massacre has been cited 1540 times. It would be fun to create a visualization of this book!
