NOTE: eBook Central is a very good platform...but in order to utilize capabilities like highlighting, annotating, etc., you will have to set up an individual account. Doing this is relatively simple (and FREE!) but it will be necessary. For most (perhaps all?) the books in this collection, you will be limited on the number of pages you can either print or download as a PDF. Therefore, if you really need to utilize the entire book, you'll want to have an account set up.
