Several new databases have been added to the Leatherby Libraries’ ongoing subscription to the ProQuest Social Science Premium Collection. These new databases are excellent resources for students and faculty doing research in the fields of government, political science, linguistics, and more. Read on for details about each:

  • Policy File Index is a resource for U.S. public policy research that provides access to information from over 350 public policy think tanks, nongovernmental organizations, research institutes, university centers, advocacy groups, and other entities.
  • The ProQuest Library Science Database includes publications relevant to library and information science, covering topics relevant to the theoretical and applied study of library science, including trade publications aimed at the library profession as well as scholarly journals.
  • The ProQuest Linguistics Database contains full-text journals and other sources in linguistics, including many titles indexed in Linguistics and Language Behavior Abstracts (LLBA). It covers all aspects of the study of language including phonetics, phonology, morphology, syntax, and semantics.
  • The National Criminal Justice Reference Service (NCJRS) Abstracts Database covers literature related to research, policy, and practice in criminal and juvenile justice and drug control from over 189,000 U.S. and international publications. It includes federal, state, and local government reports, books, research reports, journal articles, audiovisual presentations, and unpublished research. Though Chapman University has long included a link to the open access version of this database in the Database A-Z list and relevant subject guides, this subscription version from ProQuest may contain full text versions of some items that are only available as abstracts in the open access version.

One other ProQuest database has also recently undergone a name change. The PILOTS (Published International Literature On Traumatic Stress) database is now known as PTSDpubs. However, to avoid confusion, it is still available at the same URL as before: Produced at the headquarters of the National Center for Post-Traumatic Stress Disorder and sponsored by the U.S. Department of Veterans Affairs, the goal of this database is to include citations to all literature on Post-Traumatic Stress Disorder (PTSD) and other mental health sequelae of traumatic events, without disciplinary, linguistic, or geographical limitations, and to offer both current and retrospective coverage.
