Q. How can I locate a book if I don't know the title, author, or ISBN?

You can try a couple of ways to locate the book.

First, If you know the name of a chapter in the book and know it's about nutrition, use Google to do a search for "insert name of chapter" AND nutrition.  Likely, you will be able to retrieve the title of the book from the list Google generates.  You can then search the library's online catalog, OneSearch, for the title of the book.

You can also do a search for the subject of the book in OneSearch, and use the filters on the left to select books.  It will give you a list of eBooks and physical books COM library has for that topic. You may find the book in that list.
