[Web4lib] Automating the discovery of bad DOI links

[Stacy Pober]

When I tested the links in a recent update file of MARC records for
our SpringerLink books, 32 of the first 60 records had bad DOI links.
Springer had not bothered to register the DOI links.

They've since corrected this (at least for the 32 links I reported)
but I was only testing a small sample of records from a much larger
file.  I don't much fancy the idea of having to have to have someone
click through all 2000+ records in this update to check the rest of
the links are working,  And I don't have confidence that Springer
fixed all of the bad links, either (in fact, I know they didn't - I
reported 4 links that were denying us access to subscribed content and
those have not been fixed.)

So I'm wondering if there is some software that can automate the
process of finding bad DOI links to start with.  Bad DOI links do not
produce a 404 error but rather a page with the title, "DOI Not Found"

I use an automated link checker (Xenu) to find 404 errors and
redirected pages.  Is there some program that can be set up to check
links and look for a specific string in the title or body of the web
pages?
