Hi Michael,

Hmm... well that doesn't seem right at all, does it?  Thank you for
pointing it out, I've sent this along to our petabox team to see if they
can put up the correct error codes.

Peter,

I've seen no official information or documentation from the Internet Archive
either. I've actually been quite frustrated by several issues for a while
now. For example: If you go to
http://www.archive.org/details/nonexistentidentifier you'll get a
human-readable web page stating that the item cannot be found. That page,
however, is served up with an HTTP status of 200 OK, not 404 NOT FOUND.

In addition, I've noticed that when certain requests fail due to system load
and other issues, I get back an HTML page saying something like "the system
is experiencing slowness," but again with a 200 OK instead of a 503 SERVICE
UNAVAILABLE (ideally with a Retry-After header).

These things alone make it extremely difficult to automate any large-scale
metadata retrieval from the Internet Archive, and that's without any attempt
to download content.

I'm working on a post documenting some of the techniques and strategies that
have worked for us, but it's not quite ready for human consumption yet.

Michael

Subject: Re: [CODE4LIB] Internet Archive collection codes?

While we're on the subject, are there any more up-to-date instructions
for harvesting from Internet Archive than these?
http://biodiversitylibrary.blogspot.com/2008/03/harvesting-process-from-
internet_14.html

And does IA provide guidelines for harvesting (traffic limits etc.)? I
clicked around the site a bit and didn't find them, but could easily
have missed them.
