Google Books will provide you with partial access to many books published in the last few decades and full access to certain titles that are in the public domain.
It's a good way to get a sense if the book(s) you are interested in are actually useful.
If you do find something in Google Books that you like and want to see the actual book, you can always order it through Interlibrary Loan.
