Be sure to use Caps for AND, OR, NOT when searching.
AND - searches for books and articles containing both terms. Example: Queer AND Theatre
OR - searches for one of the words. Example: Theatre OR Theater
NOT - exclude a term. Example: NOT California
Parenthetical notes () - excellent for OR or NOT searches. Like a math equation, the database will do this part first.
Example: (GLBT* OR queer) AND (Theatre OR theater) = search GLBT* theatre or GLBT* Theater or queer theatre or queer theater.
Quotation Marks ""- Links words together in the search. Works best for phrases or proper names.
Example: "National Queer Theater"
Example: "Gender Identity"
Warning: You might exclude results. A search for "transgendered person" will exclude "transgender person"
Asterisk * - Allows you to search several word endings at once, without using OR repeatedly.
Example: LGBT* will cover: LGBT, LGBTQ, LGBTQ+, LGBTIQA+
Example: Bisexual* will cover: bisexual, bisexuals, bisexuality,
Example: Trans* will cover Transexualism, Transexuals, Transgender, Transgender People, Transvestism,
Warning: You may get unexpected results. Trans* will also include transatlantic, transportation, transfiguration, and about 1,025 words also beginning with Trans
Many Databases have extra hidden search commands that only work in their database. These are extremely useful BUT differ between databases, so consult the directions for each database before using these commands.

Please note that many databases works differently, so you need to read the about page. For example:
