Which tool to choose? Try both -- you will get different "book" results from the same search in the two databases.
The preferred method for searching these databases probably is a 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 keyword searches:
You can discover books (and other materials) not available in W&L libraries by using the WorldCat database, which contains the holdings of hundreds of library catalogs -- books, DVD's, digital materials, etc.
W&L researchers have access to two forms of the WorldCat database:
W&L researchers can request most items found in WorldCat via Interlibrary Loan.
Interlibrary Loan (ILL) enables current W&L undergraduate students, faculty, and staff to use other libraries' collections to borrow books or other printed materials and/or receive electronic copies of articles.
Fill out the form with as much information as you know about any book not in our collection. Turnaround time for borrowing books (from request-to-arrival) usually is about a week, although that is not guaranteed.
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.
