CONDUCTING LIBRARY RESEARCH: Using Electronic Databases
Searching electronic databases requires the following:
Searchable Fields/ Searching Techniques
Understanding the searching protocol of each database is important for a successful search. Most databases offer a number of access points such as author, title, subject, publisher, etc. As discussed in another section, databases have controlled vocabularies to be used in searching by subject. Help screens and database tutorials are usually available on each database.
Field Searching: Author/Title/Subject
When conducting author, title, or subject searches, a computer system searches a database according to the instructions of the researcher. When a researcher enters terms in specific fields, the computer retrieves information from only those fields identified:
Keyword searching allows you to use natural language key terms and locates these terms in the key fields of a bibliographic record. These key fields vary with each database but usually include author, title, subject, call number, publisher, and note fields such as summary or content notes. Use keyword search:
Reminder: Once you have located one record specific to your research topic, review the subject heading or descriptor fields. In those fields you will find the controlled vocabulary terms. Reenter your search using the controlled vocabulary terms. With the Library of Congress subject headings, only the main heading needs to be searched. It is important to remember that a key term in one database may not be the term used in another database. For example, if you are researching the topic teenagers in ERIC, the thesaurus will refer you to the term adolescence.
Additional Searching Techniques
Qualifying Limits: Most databases will allow you to qualify your search through limiting the search parameters by:
Truncation: Sometimes in searching words in a database, you would like to retrieve the records of all variations of a word, such as sociological, sociology, or sociological. Most databases allow for trunk of words to be searched. The symbols can vary between databases ($, ?, +, #, * are most frequently used).
Boolean operators are used in searching electronic databases. Boolean operators help the computer understand the relationships between terms. Combining search terms using the words AND, OR, and NOT sets up the relationship between the terms:
1. Create search command combining descriptor terms or keywords by using boolean operators: AND; OR; and NOT. Examples are: art AND social aspects; psychologist OR psychiatrist; music performance NOT music education
2. Create a search command combing descriptor terms or keywords by using both
the AND and OR boolean operators.
Example: art AND (social aspects OR political aspects)
3. Truncate the following terms for a keyword search in the online catalog.
behavior and behaviour: (British or American word)
psychologist or psychology or psychological
Documenting your research
As you begin your research, it is important to document your searches. Your professor will offer more detailed guidance, but it is important to document the database, key terms or subject headings searched, and the number of records retrieved. Troubleshooting begins with a review of the database and search term, in order to find out why too many or too few records were retrieved with any one search.
SEARCHING INDIVIDUAL DATABASES
Library Online Catalog
Once you have a basic research topic, your library research can begin. You may want to consult an encyclopedia or dictionary in the Libraries' reference collection to assist you in locating terms that best suit your topic.
The next step is to locate books that are owned by a library within your area. The CAT, the Penn State University Libraries online catalog, is available from remote access at the following URL: http://www.libraries.psu.edu. Click on The CAT and review the search options presented to you. Library catalogs usually allow searches by author, title, subject headings, and key terms. Some catalogs allow searches using qualifiers that narrow the results by applying limits to the search. These limits may include format, language, and dates. Check the Library of Congress Subject Heading volumes to locate the terms recommended.
1. Search The CAT to locate all dissertations written at Penn State in your field.
Subscription Databases: Authentication
Most electronic databases are available through subscription. A login and password are required for anyone wanting to access these databases. The login and password system restricts use of the electronic products to Penn State users. Students accessing these databases from the Libraries can access the databases without authentication.
In accessing the electronic databases, you may be asked to enter your Access User ID and Password. Your Access User ID is the part of your Penn State e-mail address before @psu.edu, and the Password is the same password for that account. For more thorough instructions, see the Remote Access Tips on the Librariesí web site. In the instructions on searching databases in this tutorial, you may assume that this procedure for login/password is required prior to entering any of the Librariesí subscription databases.
Searching FirstSearch Databases

Additional FirstSearch Techniques
Sort: From the List of Records screen, most databases allow for sorting searches between 2 and 500 records by number of libraries, author, date, source, and title.
Limit: From the List of Records screen, Most databases allow for limiting searches by author, subject headings, year, record type, language, and items in your library.
Rank: At the Advanced Search screen, FirstSearch databases allow for the following options: no ranking; ranking by relevance; and date. Ranking by relevance organizes the results of a search based on these criteria:
1. Choose the preferred records by clicking on the boxes; Mark All marks all records.
2. Click on Marked Records to bring up list; this list can be emailed or printed.
3. Click on Detailed to create the full records of all titles on the list.
4. Clear Marks removes the marked records.

Citation indexes are unusual because their primary function is to show cited references ≠ that is, they list all citations referenced in an article. You may search to find out: 1. where a work has been cited; 2. all titles cited in the references; and 3. sources that have been cited by author. Although not specifically a subject database, you may use Web of Science to locate materials by subject.
Electronic Journal Packages
There are several electronic journal packages accessible from the E-Resource List. These packages allow access to individual issues of electronic journals and a search engine to search that package by subject. Two humanities packages of interest are JSTOR and Project Muse.
JSTOR: JSTOR is an archive of the backfiles of over 242 scholarly journals in 26 disciplines. The journal articles are available in a format which includes images.
Project Muse: Project Muse is an electronic journal package that includes nearly 200 electronic journals published by Johns Hopkins University Press and 30 other scholarly publishers.
