First-time author Snow (Sch. of Information Studies, Dominican Univ.) has written an immensely helpful title on constructing Library of Congress (LC) call numbers for novice catalogers or anyone seeking a better understanding of the LC classification (LCC) system. This slim volume is packed with essential information and illustrated with numerous examples. Snow first explores the components of LCC, then guides readers through assigning class numbers and constructing Cutter numbers using LC classification schedules and tables. Although Snow provides screenshots from the Classification Web and offers advice on navigating that resource, her instructions are easily adaptable to use with the PDF schedules available on the library's website. The book also contains links to the Classification and Shelflisting Manual for additional material on specific topics and a final chapter of recommended resources for further learning. Most valuable of all, however, is Snow's straightforward, comprehensible instruction style. Each new concept builds on the principles of previous chapters and reiterates important points. VERDICT Highly recommended for library and information science students and professional catalogers in need of a refresher.-Sara Shreve, Newton, KS © Copyright 2017.
