A bibliography is a list of the books and articles that are referred to in a particular book. In your case ,if you are just listing BOOKS then you could use the term "bibliography" as a precise description of the enlisted items.
A reference is a word or phrase, that comes from something such as a book, and which you use when making a point about something.
It is not very adequate to use it in your project.
You could also use a more general term : "Endnotes" .
It could include those books in addition to references and comments on your writings.
