For the past three decades, ARBA has kept librarians up to date on the latest reference materials by providing high-quality, critical reviews. The 2005 edition of ARBA continues this great tradition by providing users with access to more than 1,600 reviews of both print and online resources, written by more than 400 academic, public, and school librarians who are experts in their field. With coverage of nearly 500 subject disciplines, ranging from the social sciences and humanities to science and technology, users are guaranteed to find information on the latest resources available in the areas they are most trying to expand their collection. With ARBA in hand, collection development librarians can maintain their library's high standards of quality and make the best use of their budget.
