The W&L library catalog lists books (and other materials) in Leyburn Library, Telford Science Library, and the Law Library.

The preferred method for searching Annie probably would be the Keyword option, which allows you to combine terms and/or to search for various forms of a term.

You can use an asterisk (*) in Keyword searching to substitute for 1 to 5 characters, thus allowing you to expand a search.
Example: environment* will find environment, environmental, environmentally, environmentalist, etc.

Here are some sample searches:

• gifted* -- forms of a word, with this result
• gifted* AND (emotion* OR psycholog*) -- using near-synonyms, with this result 
• "learning disab*"  --  multi-word phrase/term, with this result 

Doctoral dissertations are not published books, but can be considered book-length scholarly studies.
W&L subscribes to a database which offers the complete texts of over 1 million dissertations and theses.
