Volume 6 of the series Creating the 21st-Century Academic Library is focused on academic library technical services operations, and ways that they have been transformed and reimagined for working in today’s higher education environment. The literature on the place and role of technical services, technical services librarians, technical services staff, and technical services operations has expanded and grown in the last few years as decreased budgets, a focus on essential public services, and information discovery on the Internet has driven the profession to re-examine the need or importance of this back-end (or hidden) library department. Topics discussed in this book include frameworks for the networked environment, roles for metadata librarians in the areas of research data and digital initiatives, the renewed focus on the discovery of information and its place in academic libraries, the new “normal” in academic library technical services operations, emerging roles and opportunities for technical services managers, the re-training and re-skilling of technical services staff, hidden collections and needed or unexplored areas of expertise with technical services librarians and staff, the faceted application of subject headings (FAST) and obsolete or outdated subject terminology within Library of Congress Subject Headings, and a conversation about downsizing and moving forward within a law library technical services unit.
