Ok, yes, sometimes books have way more than you need!

Use the book's table of contents and the book's index to see if its contents will likely be useful to you.  Often a chapter or two are all that you'll need, rather then the entire book.

And some are available online:  when you search in MARQCAT (there's a search box below too), add the phrase 'and e-books' to a keyword search, and see if that works.  (It may not, because we do have far more books in print than online ...)  Here's an example of such a search, using e-books and supply chain.

Google Books is a great resource for finding books and gives a preview of what the book is about and often short sections to view.

There is a link to see if your local library library owns the book and you can see if any of the local libraries have the book!
