I run a website that is a directory of free programming ebooks. I only list books, full books...not partial books...not tutorial sites.
Everything on the site is legal. I don't list anything that wasn't intended to be made free, by either the author or publisher.
I received an email request today for ebooks on ABAP.
If anybody knows where on the web I can find some free legal ones, the help would be greatly appreciated.
Just leave a link to the site, with the title of the book, in a comment to this post.
