The teacher librarian sustains a healthy collection through an effective maintenance program.

I hate to throw things away. How do I know when something should be pitched?

There's a really old video on first aid that the fifth grade teacher is still using. It's inaccurate in some sections. What should I do?

One of my buildings is closing. How do I get rid of everything?

The collection must be examined periodically to determine what materials need to be repaired, replaced, or removed. Whether you're examining the copyright dates on your book collection or editing broken links at your library website, maintenance is an essential aspect of collection development.

You also need policies that help you in the reconsideration process. A statement regarding the need for reevaluation of materials should be part of your selection policy. It should also indicate specifications for periodic inventories and recommendations for continuous and intermittent examination. Finally, criteria should be included for deselection of materials.

What is weeding?

space flightWeeding or deselection is selection in reverse. It is the practice of discarding or transferring to storage excess copies, rarely used items, and materials no longer in use.

For example, the book on the left titled Space Flight: The Coming Exploration of the Universe by Lester Del Rey (1959) was found in the science section of the library. The information in this book is nearly half a century old.

Purging is officially withdrawing an item from the collection. You'll want to destroy or deface purged materials to avoid "haunting materials." These are items that mysteriously reappear in your check-in bin years after they were discarded.

A policy is an important part of the weeding process. If you don't have a policy statement, how are you going to respond to questions?

Weed now or weed later?

The answer to this question is WEED NOW! There are two laws of nature concerning weeding. First, no matter how strange, one person will find the item useful. Second, no matter how long you've had it, ten minutes after it's gone, someone will want it. Don't worry, it happens.

How do you deal with guilt over tossing materials?

Weeding involves guilt. You feel bad because you are throwing away books, videos, or software. Think about it. Do you want a student to get inaccurate information? Do you want a little girl to think she can't be a doctor because only boys are represented as doctors in the career book she is reading? Do you want students to handle old, moldy books? At times, there are so many old books that students can't find the good ones. Weeding is essential.

What excuses can be used for not weeding?

"Weeding is defined as the ongoing process of removing resources from the collection. What is also ongoing, unfortunately, is the recurring outcry from the public over weeded resources. Visions of headlines such as "Librarian Trashes Precious Books" and scores of parent protesters guarding school dumpsters can turn even the most determined library media specialist into an equally determined weeding procrastinator."

Gail Dickinson (Apr / May 2005). Crying Over Spilled Milk (PDF document). Library Media Connection; 23(7), 24-26.

There are many excuses for not weeding. You may say you don't have time. In the long run weeding saves time by helping you see what you've got. you won't keep wasting time with old materials. You may say you're scared of making a mistake. Deselection criteria will help you make good decisions. You may fear throwing things out. Purging just takes practice. Repeat to yourself, quantity does not insure quality.

Remind yourself: like a healthy garden, a library must be weeded.

What should be considered in weeding?

There are some things that should not be weeded. However, you may choose to move them out of general circulation. The following list provides some examples.

What should be weeded?

Consider the physical condition, qualitative worth and quantitative worth of the item.

First, check the physical condition. Should it be repaired, replaced, or tossed?

Second, think about the qualitative worth of the material. Do you have anything else on the topic. Is the information negative, harmful, or subjective?

Third, examine the quantitative worth. Do you need multiple copies for classes or could you toss the copy in the worst shape?

What kind of weeder are you?

There are many types of weeders. What kind are you?

Weekly Weeder. This person has a schedule for weeding. For example, every Friday afternoon might be devoted to weeding. Or, Tuesday morning after the staff meeting.

Whenever Weeder. This weeder knows that weeding need to be done, but doesn't seem to be able to fit it into the schedule. There's a master plan, but it may take years to get it done. Weeding may take place when there is no other choice. For example, if you're looking for something, you might weed the poor items around it. Or you might week the video collection when the shelf is full.

Quarterly Weeder. This person has a schedule like the weekly weeder and keeps on the schedule. It will be done, slowly but surely.

Inventory Weeder. Weed while doing inventory. This makes inventory take longer, but both are accomplished at once.

Major Project Weeder. The person does weeding as part of a larger project. For example, they may dive into the geography section as part of a project focusing on social studies standards.

Are there special considerations for weeding equipment?

Many school district have policies regarding discarded items over $200 or $500. There may be special discarding procedures such as taking the item off a district inventory list or sending it out for sale. In addition, there may be special paperwork for removal from inventory. You should keep good records on equipment repairs so you can justify removal and new purchases. These records should include who, where, when, why, and how much questions regarding equipment. Always weigh the cost of repairs versus cost of replacement. It is often cheaper to buy new.

What is the CREW Method?

The acronym CREW stands for Continuous Review, Evaluation, and Weeding. CREW is a cyclical process because one step leads to the next. The complete cycle is "collection building." The CREW method is a series of ongoing processes that continuously adds to, removes from, adjusts, and interprets the collection to fit the needs of users.

A full explanation of The CREW Method is found in the print book The CREW Method: Expanded Guidelines for Collection Evaluation and Weeding for Small and Medium-sized Public Libraries by Belinda Boone, Texas State Library (1995).

What should be done with weeded materials?

Once an item has been de-selected, a few record-keeping cleanup and property identification steps should be completed. Remove the item from the library catalog system. Clearly identify that the item has been removed or discarded from the collection; some libraries use an ink stamp for marking the title page and at least one other location, and on each separate part. If the library has a security system, then remove or erase the security device. The aim is to mark the item(s) in a way that if somehow they are brought back to the library, it is quickly recognized as having been removed and discarded from the collection.

Next is the question of what to do with the unwanted item. Many recommend that if a material is to be truly discarded, if the item is not fit for anyone's use - - it should be thrown in the trash. But nuisance problems can sometimes occur when others notice the items in the trash. One option is to destroy the item, damaging it to point that it is not reusable! It's okay to throw them away. The item has not been used in five or ten years, no one bought it at the book sale, it's not suitable for use by anyone. But what about other situations?

Some other options for consideration:
Recycle old, outdated, unwanted books
Hold a book sale (Lower the cost during the last hours; $1 a bag of books)
Set out leftover books in a 'Free' box
Donate books (Groups like Books for Africa and Books for Soldiers)
Goodwill or Salvation Army stores (Contact to find out if they will accept items)
Jail or prison (Again check to see if they will accept)
Nursing homes
Sell books through Powell's Books, or Better World Books

It is usually a good idea to insure that school administrators understand and support the concept of collection weeding and also are aware of the strategies being used to dispose of de-selected items.
