Based on the principle of non commercial exchange, ELP aims to become a forum where donators and interested parties can contact one another. It encourages the donation of collections of books by organizations and by those who do not have a necessity to keep them. In return, it allows organizations with specific needs to take advantage of these wonderful donations.
ELP is open both to individuals and public and private organizations willing to acquire or to discard coherent collections of books (collection / themes) and/or libraries materials. With free access, this program contributes to the share of knowledge and the redistribution of cultural wealth.
