When I heard a librarian mention the word weeding for the first time I felt completely confused by what that could mean. One year later and I have a much clearer understanding how important this is for every library collection. So why does a collection need weeding?  Quite simply we need to deselect those items that are not required so there is space for the new ones that have been carefully curated to fit in the collection.  Weeding is often referred to as deselection or culling (Croft, 2017).  If it is your vegetable garden you need to get rid of those weeds so there is space and optimal conditions for the plants to grow. In your library those weeds need to disappear to help your students and staff grow by providing them with a relevant, attractive and accessible library collection. Students should not be dealing with crowded shelves and old and unappealing books.  When they can’t locate what they are looking for in cluttered shelves with old books, they will make the assumption that the library collection will not have what they need. Therefore weeding is a very important aspect of collection management (Renate Beilharz, R, 2007)

Many libraries undertake weeding in different ways but a method called CREW (Continuous Review, Evaluation, and Weeding) is, in my opinion, the best way to manage the collection.  This will ensure that weeding is not a job not to be done only in stock take or every few years as an enormous job.  Applying CREW will make the collection constantly relevant and mean that weeding is happening regularly (Larson, 2012).  TLs should be using a collection management policy that has a section on weeding. It should include a selection criteria and all weeding should be documented.

It is just as important to weed electronic resources including ebooks, audio visual materials and websites linked to the library collection. Baumbach & Miller discuss that quality is more important than quantity and argue that “misleading, inaccurate, out-of-date information is never better than no information” (2006, p.6.).  This involves looking at the non-fiction collection carefully and deselecting anything with outdated views. Science and technology topics change more rapidly than the arts and literature so will need to be updated more often (National Library NZ, 2014). Braxton(2016) provides a useful guide with timelines on when resources should be replaced in her Sample Collection Policy blog.

“Most weeding criteria used by libraries involve a combination of qualitative and quantitative weeding criteria. Commonly used qualitative weeding criteria have been expressed in the acronym ‘MUSTIE’. This is a useful guide to help develop weeding guidelines in any library. MUSTIE stands for:

• Misleading – factually inaccurate
• Ugly – worn beyond mending
• Superseded – new edition or better information
• Trivial – no literary or scientific merit
• Irrelevant – to needs of school
• Elsewhere – material easily borrowed or available from another source” (Renate Beilharz, R, 2007).

Quantitative criteria based on numerical or statistical measurement is a very useful way to weed. The Library Management system should be used to identify which resources have not borrowed for three to five years.  Some resources may need to be promoted before a decision is made to discard them. Weeding also involves identifying resources to be replaced or repaired.  When making the decision to discard materials, resistance can come from staff who do not understand the importance of this aspect of collection management.  It is part of the TLs role to educate why these decisions are being made.  Having a selection criteria and a policy in place is important to back up all decisions.

Another aspect that needs to be considered when weeding is the reading level and subject matter. At Dulwich College (Singapore) we have three libraries for the different age groups.  We are moving books from our Junior School Library to the Infant or Senior Library on a regular basis. This is probably happening more often because the school is only three years old and the collections were originally created before the librarians started at the school.
