Use the CATALOG TAB on discoverE to find books, journals (titles only, not contents), videos, cds and other materials at all the Emory libraries.
OR search Google Books, and if you find a good one that is NOT available fulltext, you can search that title in discoverE.
You DON'T HAVE TO READ THE WHOLE BOOK!!!
Another useful resource for medical e-books is AccessMedicine. There is a books tab that you can use to search specifically for books.
NOTE: These books are all listed in discoverE too, but in AccessMedicine you can search the contents of the books.
