This article is based on a course on how to use Moys classification scheme,1 delivered by Helen Garner and Felicity Staveley-Taylor on behalf of the British and Irish Association of Law Librarians (BIALL) in November 2022. The article, which is also written by Helen and Felicity, provides guidance on how to use Moys classification, explaining the features that enable the scheme to be expanded to accommodate new subject areas. The article also explains some of the features which ensure the scheme remains relevant to legal libraries today. Sections from the classification scheme, as published in the fifth edition, appear in the article text. In addition, any references to page numbers are to the fifth edition.

In this article Harpreet Dhillon recounts the experience and impact of Middle Temple Library's transition from an alphabetical organisation of textbooks to a subject order using the Moys Classification Scheme.

The McCann FitzGerald library provides a library and information service to one of Ireland's premier law firms. As Megan Guthrie explains, it was decided to reclassify the library collection using the Moys Classification Scheme for Legal Materials1 to enhance and improve the flow of the collection. It also provided an opportunity to conduct a stocktake of library material. The project was broken down into three main steps: assigning a Moys number, relabelling the physical material and updating the library management system. There were a number of challenges including the need to modify or add to the Moys numbers and finding the optimal process for relabelling and accounting for the material. It was necessary to adapt the initial plan throughout the project to account for any obstacles or restrictions that were encountered.

This article, written by Helen Garner, reviews the progress of the Moys Reclassification Project at the Bodleian Law Library and covers the issues relating to the lessons learnt and the benefits of changing to a different classification scheme. The Bodleian Law Library started work on the Moys Reclassification Project in 2006 and work is still on-going to complete the project.

Ruth Bird, Bodleian Law Librarian, explains how the original home-grown classification scheme became unfit for purpose, due to the enormous expansion of international legal materials held, and the reasons for implementing the Moys scheme. She outlines the progress and the problems encountered to date in this huge project.

Catherine O'Sullivan of Norton Rose outlines the benefits of using the Moys scheme in a large law firm library. She also briefly discusses how the firm has tailored it to their specific requirements and she finishes by pointing out the potential disadvantages of the scheme.

Vanda Broughton describes the methodology of constructing a thesaurus from a faceted classification for law (Bliss Bibliographic Classification 2nd ed. Class S). The structure of the classification is described, and the way in which the thesaural relationships are derived from this is demonstrated. Recent work to automate the process, using the encoded classification data used for the schedule display and alphabetical index, is explained. Examples of the way in which this functions are included, and an analysis of the output shows where editorial work will help to improve the resulting thesaurus.
