Use the One Search and limit to BOOKS to find sources on your topic.
I suggest starting with one keyword or keyword phrase, and building your search as you assess your results each step of the way.
For the sample search below:
(Click on image to enlarge)
Clicked on a title to open the "record" to learn more about the book and decide if it looked useful!
Search for print books, ebooks, and videos available at the library and online.
Use filters on the left to limit by specific source type, date range, and more.
I start my searches with Keywords that capture what I want to learn about.
I also look for useful Subject Terms to find everything on that subject in that database.
