Q. Can I download entire library e-books to my computer or e-reader?
There is no simple answer to this question, because our e-book collections vary greatly. Some only permit reading the e-book online in a web browser. Some permit downloading individual chapters of an e-book as PDF files, but the entire e-book is not available as a single file.
Ebrary is one provider that does enable downloading of entire e-books in the Epub format, which many e-readers (but not Kindles) can use. However, the rights to do this are set by the book's publisher, not Ebrary, and there is no definitive list of which titles are available this way. Also, be aware that Ebrary downloads are similar to checking out a physical book. Some are available for seven days, some for fourteen days. After the "checkout period" your access expires; no titles can permanently reside on your computer or e-reader.
There are a number of steps (and software applications) involved in downloading entire Ebrary titles to your computer or e-reader, as described here.
