Getting the Most from Database Searching

Harvard subscribes to thousands of bibliographic databases to assist you in finding secondary sources (journal articles, books, working papers, proceedings, book and film reviews, etc.) on your topic. This page introduces you to some of the most useful sources for literature and philosophy. You may also browse for more databases by title, keyword and subject using the tabs you find here:


Using E-resources Effectively

To use e-resources effectively:

Read about their scope (subjects covered), types of sources indexed (articles, books, dissertations, etc.) and coverage (dates of publication).

Use keyword searches and observe the results; browse records, subjects and abstracts for additional search terms.

Refine your searches using these keywords and subject terms. Narrow with limits, or remove limits for a broader perspective on a topic.

To locate the article, book or other source, use the link.

If working from a print citation, use the Citation Linker tool to locate full text of an article quickly. You may also search for journal titles (but not articles) in HOLLIS or HOLLIS Classic.

Dissertations and Theses

Dissertations are among the most productive secondary resources you can find.  If you identify a recent thesis on your or similar subject of inquiry, you will have an extensive list of bibliographic references to start your research.  Of course, you will have to complement any sources you identify in this manner through your own research and to update the information in the thesis (or theses) consulted.

To find doctoral dissertations from North American universities and some European institutions, search:

For Harvard theses, honors theses are listed in HOLLIS and HOLLIS Classic. For others, inquire at the Harvard University Archives.

Philosophy Indexes and Abstracts

Philosopher's Index
The Philosopher's Index provides bibliographic information and abstracts for articles and books on philosophy published since 1940. This is the electronic version of the print edition found in Robbins and in Widener. While most of the citations are complete, not all of them have complete or well-done bibliographic information. You may need to piece together what work the citation references from other sources.

The Philosopher's Index recently launched an upgraded search interface. Now, there are three search options: basic search, advanced search, and index search. The basic search allows the user to search by keyword only – this generally returns a greater number of hits, but is useful for general searches to get a feel for what might exist on a topic. The advanced search functionality, on the other hand, has pull-down menus and a more sophisticated layout that allows for more targeted searching. The index search allows the user to search several of the database's indexes to see how many articles exist in the category listed. This is useful, for example, to see how many times an author has published, how often authors use certain descriptors, how many times articles from the respective journals are listed, etc.

The layout of the new interface allows for easier navigation of the database and greater customization of the search page. The clumsy buttons and antiquated layout of the old interface have been replaced with new GUI (graphic user interface) formats that facilitate use of this database.

Additionally, once you have a citation in Philosopher's Index, you can click on "Find it @ Harvard". This means that, if Harvard subscribes to the journal referenced in the citation, the user will be able to directly link to the citation from the Index, rather than having to log out of the Index to get to the appropriate source. However, "Find it @ Harvard" generally appear next to a citation regardless of whether Harvard subscribes to the publication – the user will not know if there is electronic access until she tries to access it via this means.
