cb put me on to Chantraine’s Dictionnaire étymologique de la langue grecque. Today I stumbled upon a complete version and dozens of other downloads. The Chantraine is down the page and the link is to archive.org, but not all of the links are to there:
http://www.lexilogos.com/english/greek_ancient_dictionary.htm
They have lots of other languages too:
Erm. Some of these are pushing hard on copyright dates, and some are outright rip-offs, unfortunately,
Yeah, I wasn’t sure. But the vast majority of the books are in the public domain. And many of the links are just to good web sites with dictionaries, etc. Curiously, the most recent one is the Chantraine and that is hosted on archive.org. I’m not sure how copyright works internationally. Perhaps French copyright law is different? It is not like they are a torrent site or something.
Well, Bakker’s Companion to Ancient Greek is nowhere near out of copyright — it was published last year.
That is hosted on scribd.com. I’d never seen that site before, but they sure are pushing Facebook as that is the only way to login and download. I read their statement on copyright and it is the same approach as youtube (which is owned by google):
“Each time Scribd receives a DMCA-compliant takedown request from a copyright holder, we quickly remove the unauthorized document” This approach has been upheld by the courts. But, according to Wikipedia:
"Scribd often has been accused of copyright infringement. In March 2009 Scribd launched a copyright management system and has made upgrades to the system including the addition of OCR. The New York Times reported in May 2009 that Scribd hosted pirated works by authors such as Ursula K. Le Guin.[38]
In September 2009 American author Elaine Scott alleged that Scribd “shamelessly profits from the stolen copyrighted works of innumerable authors.”[39] Her attorneys Joe Sibley and Kiwi Camara sought class action status in their efforts to win damages from Scribd for allegedly “egregious copyright infringement.”[40][41] On May 11, 2009, Motoko Rich, writing in the New York Times, reported on Scribd hosting pirated works. Sibley Camara filed a class action lawsuit against Scribd, accusing it of calculated copyright infringement for profit.[42] The suit was dropped in July 2010.[43]
Since its inception Scribd has been served with 25 DMCA take down notices.[44] In June 2010, SCRIBD tickets related to copyright infringements exceeded 66,000."
Since sites like scribd and youtube(google) are actually doing the hosting, they are actually abusing copyright holders more than a site like lexilogos that just links to it. And given the absurd copyright laws that we have actually, it seems all are acting perfectly legally.
The law is no substitute for moral thinking. Aristotle might have thoughts on this, too. 
Hmmm, I don’t have any knowledge of what Aristotle would have thought about copyrights. I do know that if it weren’t for copyists, we wouldn’t have Aristotle. 
Oh, and there are other places besides Scribd to get some of the newer books.
