A basic, keyword search with OneSearch means using words or phrases you've come up with to describe your research topic. It's not a very precise way of searching, but it usually returns many search results to examine, which can lead to precise subjects that will help you build more targeted searches; find a source that appears promising from your keyword search results, and check that item's list of subject terms.
Subject searching is very precise; subject terms are assigned to a source to describe the item's main content. Usually there won't be many search results when conducting a subject search, but the items returned should definitely be on target with your research topic. You can try an advanced search in OneSearch using only subject terms. An advanced search works best when you enter the exact subject term used in the catalog.
The following are Library of Congress subject terms related to our topic. Some terms contain an asterisk (*) at the end: adding this symbol at the end of a word will search the root of this word and all other endings for that word. For example, lesbian* would also search for lesbianism and lesbians.
