The Library Catalog allows you to search for books, government documents, DVDs, electronic books, and other materials in the Library's collection. The catalog will tell you if the library owns a particular periodical (journal or magazine) but does not include the articles found in periodicals. To find these you must use a different database (click on the "Finding Articles" or OneSearch link to the left). 

The Advanced search screen allows you to combine terms using “and, or, not” as well as limiting a search by material type, language, and/or date.
