This latest edition of American Reference Books Annual (ARBA) provides librarians with insightful, critical reviews of all reference resources released in 2015 as well as some from key titles from 2014. Highlighting both the positive and negative aspects of each resource, the volume allows librarians to make informed decisions about which new resources are most appropriate for their collection and their patrons' needs. Collection development librarians who are working with limited budgets―as is the case in practically every library today―will be able to maximize the benefit from their monetary resources by selecting the materials they need most for their collection while bypassing materials that bring limited value to their specific environment.
