Central Index replaces many subject indexes

The new Central Index replaces many subject indexes as of July, 2020.

The following indexes were cancelled, and you should now use this broad search tool:

PsychINFO, Philosophers Index, ATLA Religion Index, MLA, America: History and Life, SciFinder Scholar, Communications and Mass Media, and the Multidatabase Search tool.


Central Index

Central Index is a search tool that provides keyword searching across a wide (but not comprehensive) selection of materials: books, journals, videos, web pages, and other sources. It gathers information from many resources and allows you to search across them simultaneously. This tool is similar in many ways to the Google Scholar search tool, but offers much more precise searching.

                                  Short video showing the basics of searching and downloading materials and our Central Index searching tips

                  NOTE: You will need to login on the top right to obtain access to the full text material.

                  NOTE: Use the Expand option on the top left of the results page to locate and request materials we do not immediately own/lease.


     NOTE: This full text search tool does not utilize subject headings -- but it does offer Subject searching (for major emphasis of keyword terms) and facets on the left side of the search results page that help in narrowing your results. See the tools below for more powerful alternative search options in certain subject areas.    

  • Remember to use synonyms for your key concepts -- for example (car or automobile) and (accident or collision).
  • Place phrases within quote marks for precision. Example: "event horizon"
  • Use the Advanced search to combine concepts and search fields. 
  • Use the Subject search option to identify strong emphasis of specific search terms or phrases (in quotes).
  • Refine your initial results with both additional terms and the result screen left-side facets (sub-clusters of results by subject terms, date, material type, etc.).
  • Use subject terms found within specific articles to further narrow your results with controlled vocabulary.
  • Use the Expand My Results option to discover additional materials we would need to Borrow From Other Libraries.
  • Once you have completed your search, you may want to expand your searching using multidisciplinary news resources, and perhaps specialized search tools such as Scopus which offer enhanced discovery through creative techniques such as citation tracking.

 The Central Index is NOT the best place to start if you are looking for the following types of information:

  • news...more complete news sources are found on our News Resources page
  • facts...a collection of dictionaries and encyclopedias can be search on our Facts/Definitions page
  • journal articles covered in a core set of 800 journals (Academic Search Complete)
  • journal articles when there is deeper subject indexing...perform more precise searching in our subject indexes
  • business data is located using our business Help page
  • music performances and scores are found using our music Help page

While the Central Index covers many materials, it is not comprehensive, and other library tools provide complimentary search options for journal articles:

  •  Academic Search Complete provides searching across a core collection of approximately 800 multi-disciplinary journals, and offers immediate full text articles for most of the results. Good for basic searching.
  • Scopus searches across a wide range of journal articles, and provides immediate links to the full text of many, while offering 3-day turnaround on those we need to borrow from other libraries. It also offers ranking of articles and journals by impact based upon citation patterns. You can follow a research front using this tool.
  • More comprehensive searching is provided for some disciplines using our subject specific journal indexes.

One additional free search tool to consider is Summon (from Princeton). You will see information about journal articles, books, and other materials...but you will not have links to the full text materials.
