Why weeding?

Weeding is an important process for all libraries to undertake to ensure their collections are

suitable, balanced, relevant, and current. A Weeding Policy should be included as part of a larger Library Policy and may appear in a Collection Development and Collection Management Policy, so the intent, guidelines, and procedures are clearly outlined. Without a clear policy, TLs run the risk of harsh criticism from the wider community who may have a limited understanding of the role and importance of weeding. Weeding aims to tidy-up the collection, so that the library does not offer dangerous or misleading information (Baumbach and Miller, 2006). It also makes it easier to conduct mapping activities to determine gaps in the collection and directs future collection development (Western Australian School Library Association [WASLA], 2013). Additionally, weeding ensures resources are appealing and appropriate for reading needs, levels and interests. Poorly maintained collections do not meet the vision or mission of school libraries because they make resource selection difficult and limited. Therefore, regular weeding must occur throughout the school year and with particular criteria to direct the weeding. Texas State Library and Archive Commission created the CREW (Continuous Review, Evaluation and Weeding) method, which involves evaluating resources according to their publication date, last use and the condition (Larson, 2012). They also highlight the benefits including; saving space and time, making the collection more appealing, enhancing the reputation of the library, meeting needs, and identifying the strengths and weaknesses of the collection (Larson, 2012). Additional criteria include the MUSTY or MUSTIE test; Misleading, Ugly, Superseded, Trivial, Your collection has no use for it/Irrelevant to your context, easily obtained Elsewhere (debmille, 2011; Larson, 2012). Further to this, libraries should develop a clear set of goals they would like to accomplish with the weeding process and all people involved should have a clear and consistent vision and thorough understanding of the needs of students and the wider school community.

Models and methods for collection evaluation

Evaluation of collections assesses the extent to which library collections meet the goals of the library and the needs of the community it serves. There are various methods of evaluation that can be employed in school libraries. ALA identifies two categories of collection evaluation; collection-centered measures, and use-centered measures (Evans & Saponaro, 2014). A balanced way of evaluating the collection is to employ several of these methods and to ensure objective data is gathered in the mix. Grigg (2012) proposes methods of evaluating collections that are suitable for both print and digital resources. The methods and their usefulness in school library collection evaluation is outlined below:

Usage data: assessing circulation statistics.

  • Useful in determining the popularity of resources and the subject areas that are most borrowed and types of books used. This can be helpful in assessing how the collection meets learning needs and reading needs.

Overlap analysis: assessing duplications within journal collections.

  • Useful in minimising wasted dollars through unnecessary duplicate resources.

Survey instruments: quantitative method of collecting user feedback.

  • Useful in determining the users’ impression of the library and collection and the usefulness of the collection in meeting specific needs. This value of this method is increased when used in conjunction with another method of evaluation.

Benchmarking: comparing the collections of different libraries.

  • Useful in identifying potential gaps and strengths in comparison to other school libraries. This could be done during network meetings to provide suggestions and recommendations and collaborate with others in developing quality collections to meet the needs of the clientele.

Focus groups: qualitative method of collecting user feedback.

  • Useful in determining the strengths and weaknesses of a collection from the perspective of the library users. This method should be used in conjunction with other methods of evaluation, as the results may be bias or may only apply to a niche market.

Balanced scorecard methods: matching criteria or outcomes against circulation statistics.

  • Useful in assessing circulation statistics against particular goals; however, there is difficulty in developing realistic or accurate criteria and this does not account for the quality of the resource it only counts the use.

 

What are the practicalities of undertaking a collection evaluation within a school in terms of time, staffing, and priorities, as well as appropriateness of methodology?

Collection evaluation can be an expensive process in terms of staff time (Arizona State Library, n.d.); however, it is important to make time to ensure this process is undertaken. There are opportunities throughout the school year to allocate time to this process; for example, during staff days at the beginning of end of term, and during weeks when classes are limited (e.g. weeks 7-8) and TL time becomes available for other library management duties. This should be a priority when receiving assessment task sheets or unit outlines from teachers and when organising assignment help lessons. Methods must relate to all aspects of a school library; including, assessment and curriculum support, reading for pleasure, resources for teaching and other staff, resources to support the wider community. Additionally, the methodologies used should take advantage of the resources available to ensure the process is efficient; for example, using the OPAC to gather data and generate reports.

How does the need for, and possible benefits of an evaluation of the collection outweigh the difficulties of undertaking such an evaluation?

  • Despite the difficulties in undertaking collection evaluation it is vital in determining how and to what extent school libraries are meeting users’ needs and in cementing the library in the school context as a valuable commodity. As highlighted by Hernon, Dugan, and Matthews (2014), evaluation activities provide evidence of accountability and the opportunity to review and modify practices in a clear and formal manner. It also provides justification for changes in selection priorities and supports weeding or deselection decisions (Pattee, 2013). Collection evaluation is paramount in ensuring the collection’s usefulness and relevance to the school community.

Is it better to use a simple process with limited but useful outcomes, or to use the most appropriate methodology in terms of outcomes?

  • The answer to this question may change depending on the aspect of the collection needing to be evaluated – general or specific emphasis collections. Overall, the most appropriate methodology in terms of outcomes is the ideal method a TL would use when evaluating the collection; however, constraints including time and staffing may interfere with this. When evaluating the collection to meet curriculum needs, it is important to use the most appropriate methodology, as it is the role of the school library to meet these needs and assist teachers and students in understanding and navigating the new curriculum. If evaluation processes occur more regularly, they will become quicker and easier, as the process is streamlined and more regularly updated. Furthermore, the collection will more accurately reflect the library’s mission and changing needs of the community. Hernon, Dugan and Matthews (2014) even suggest that evaluation activities should become daily activities within libraries to review and improve services with the aim of meeting stated goals and objectives. The National Library of New Zealand recommends weeding monthly or quarterly, which could also be a useful time to undertake other evaluation processes (2012).

What are the current priority areas for evaluation in your school library collection?

  • Current priority areas for evaluation in my school library collection include, evaluation of the non-fiction collection in meeting curriculum needs of senior students studying the Arab Israeli Conflict, and Year 9 and 10 Science students undertaking new inquiry tasks requiring them to break down science claims and develop very specific research questions that require resources to support the question and their reading levels.

Collection Analytics

Formally analysing the collection using quantitative data is a powerful tool is assessing the value of the collection overall and identifying the areas in need of improvement. It also provides a means for better understanding the collection and its position in meeting library users’ needs. Collection analysis and mapping also provides a means of rectifying any bias that may be present in the collection to develop a more balanced collection overall. This also assists in collection development policies. Collection analytics provide a quantitative means with which to assess the collection, plan programs, assess budgetary requirements, compare libraries, evaluate the collection against curriculum requirements, develop library policies including collection development policies, and assist in weeding and deselection (Hart, 2003).

Hart (2003) suggests collecting data through LMS reports. Specifically, Hart mentions counting the number of resources in each Dewey class, calculating the average date of publication in each class, and collecting circulation statistics to determine “where supply was meeting demand” (Hart, 2003, p. 89). This data is then collated in a spreadsheet and analysed against a specific set of questions. Graphs are created to compare interrelated aspects of the collection; for example, age of the collection with the percentage of the collection by Dewey class, and number of titles with circulation. This last element of incorporating circulation statistics clearly allows libraries to identify how the needs of the users are being met and whether resources need to be increased and updated, and whether promotion is needed to increase readership related to particular curriculum areas.

TES recommends undertaking collection mapping that includes determining the average number of books per student in the general emphasis and specific emphasis collections, once the data is collected it can then be analysed in the following ways:

  • Examine strong sections to determine if the collection is evenly distributed,
  • Consider limiting selection in strong sections,
  • To improve weak sections, consider selecting from retrospective selection bibliographies and watch for new items,
  • Compare weak sections against the curriculum to be certain materials are needed,
  • Develop strategies to promote strong sections,
  • Compare the results with circulation statistics (Tangient LLC, 2018).

The Arizona State Library (n.d.) suggests first considering the library’s purpose and mission. This is used to provide a framework or focus for the collection analysis process. The data collected will be assessed against these standards. The types of quantitative data collected includes, number of titles, age and timeliness of materials, use, and per capita measures. These are also compared with qualitative data such as observations of use to better interpret the quantitative data.
