When I purchase paper books, I often loan them to my students. Sometimes, I get them back, and I am OK with that.
I have purchased perhaps 40 O'Reilly ebooks, which I do NOT share with students because I suspect students might retain their own electronic copy.
What ARE your policies regarding sharing ebooks? I'll follow them, but I do not find them anywhere on your site.
Information on the lending of ebooks can be found here:http://shop.oreilly.com/category/cust.... Here is what can be found concerning lending ebooks:
"Lending: If you buy an O'Reilly ebook from oreilly.com, you may lend it to another person, provided that you do not retain any copies of the book after you lend it. This is the same as the situation when you lend a used print copy—when you lend the copy, you deliver it to the buyer and no longer have a copy in your library. If you have bought a hard copy/ebook bundle, you may of course retain the hard copy, if you lend the ebook."
Hope this helps and have a great day!
