I’ve shied away from putting books on kwakk.info, the site for comics research. Magazines seem, perhaps, less controversial for a site like this? I dunno.
In any case, I’ve now downloaded a whole lot of books about comics — but only books that are at least 20 years old — and put them in their own category. And they’re are only available for searching, not for reading. (That is, you can read five pages per search result.) If anybody objects to their books being on there, drop me a note, and I’ll eighty-six it.
May the search index be with you.
