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.
