When searching for books in OneSearch, it's ok to do a quick search (or keyword search), but another powerful way to focus your search is using the "advanced search" feature. Here you can specify a subject search ("any field" --> "subject"). Another option if you're not sure of the terminology you're searching is to click "browse" (at top of screen) and then choose "browse by library of congress subjects" -- note that search results are slower this way, but it can help you decide if you're using relevant search terms.
Remember that the subject is what the book is "about," so if you're looking for books about an artist, search that person's name as a subject. Searching for an artist as author will give you results that include catalogs (such as exhibition catalogs and Catalogues Raissonné).
Baylor's libraries collections are very strong, but we don't have every book in the world. To see what's out there beyond Baylor's collection, use the WorldCat database(see link below). You can borrow books from other places in the world through Baylor's Interlibrary Loan Service (Osofast). For more info on OsoFast, see "Journals and Articles" tab.
You'll find dissertations and theses for which Baylor owns copies treated as books in BearCat. The link below provides access to specialized databases that focus exclusively on theses and dissertations and can point you to many more resources beyond Baylor.
