A Boolean library search method primarily involves what aspect?

The Boolean library search method centers on the use of specific logical operators—such as AND, OR, and NOT—to refine search results in databases and catalogs. This approach allows users to combine or exclude keywords, thereby enhancing the relevancy of the retrieved information. For instance, using "AND" will generate results that include both search terms, while "OR" broadens the search to include results that contain either term. This method is particularly useful in academic and research settings, where precision and specificity in finding relevant materials are crucial.

The other options do not align with the Boolean search method's core function; searching books by title is a straightforward search approach that does not utilize Boolean logic, organizing library events and evaluating staff performance are administrative tasks that are unrelated to the process of searching for information in library databases.
