Each book on this site represents a lot of care, effort and dedication by the authors. That work deserves respect.
The library here operates as a public library. You can walk into any public or university library, anywhere in the world, and sit down to read a book. Or you can become a member, and borrow a book.
The books in this library are available to read online (those are not downloadable), or you can ‘borrow’ a book electronically - which means that after the period of the book loan, the file will no longer be readable.
As a library, we are not in the business of renting or selling books, though we hope that through getting acquainted with the books, you may want to purchase them yourself from sites that sell copies.
In the spirit of the public library, the object is to bring knowledge into the public domain. We are not in competition with book sellers, who have an important place in the private sphere - to make books available for people to purchase.
