MODULE 2.4 - Connect words and concepts

Step 4: Connect words and concepts

Use Boolean operators - OR, AND, NOT - to connect words/phrases and concepts.

Boolean logic takes its name from British mathematician George Boole (1815 - 1864)
A system of logic designed to produce better search results by formulating precise queries.

Boolean searching
named for mathematician George Boole, Boolean searching uses mathematical set logic to combine search terms. Boolean operators AND, OR, and NOT are used in Boolean search statements to specify the logical relations among terms.

Browse searching
browse searching is limited to one field, such as author or subject heading, and the computer matches the search statement exactly, so word order and spacing are important. This is in contrast to keyword searching, which may involve more than one field, and where word order is not important. A browse search results in a list of entries from the one field, and one scroll may through the list, either forward or backward, as far as one wishes, potentially through all the entries in the list.
