e-books are electronic books. Basically they are an electronic version of an original book you would normally buy at the store (as a hardcover/paperback).
The most common format people put them out as are PDF files, but there are others (like tomeraider, plain word or txt files, etc...). I have a few am sure some people would like to read, so if section does go up & we are allowed to post, I will put them up.
PS
they can be really small (200K) to fairly large (25MB or even larger)
