I've been using a commercial package (http://pdftransformer.abbyy.com/ ) and
have been really happy with it in general.  It's slow, but does a good job
on even marginally readable text.  I don't think I've ever needed to use it
in batch mode, but I believe there's a way to make it happen, and that will
be necessary since every article is in its own .PDF file. 

The wget process copies the HTML index pages as well as the .PDFs and fixes
up the links to point to the local copies, so that part is pretty easy to
deal with.  For my own copy of the archive, I'll probably merge all of those
index pages into one document so that all of the article titles can be
browsed on a single page.
