I am somewhat confused (very normal for me) on how you are using the the term e-library. Are you wanting to set up a computer center (room with computers and software) or e-library ( a online site that provide specific information, ebooks, and audiobooks). My definition for a e-library is what I see the World Bank doing and ProQuest.

If you want to do an e-library you need to have a library of e-books loaded on a computer. There are a number of free e-books, that make great reading to get you started. They can be found at:
