On a related note, these past couple of weeks I've found myself wanting to import several years' worth of accumulated PDFs into a BibTeX file. This has involved metadata extraction, text scraping, querying Google Scholar (good, but rate-limited) and CrossRef (no limit, but not as accurate). I've written a very rough guide to the approaches I've taken so far at http://chriswarbo.net/essays/pdf-tools.html http://chriswarbo.net/essays/pdf-tools.html , with a bunch of links to external tools, some NixOS package definitions, commandline snippets and descriptions of Emacs macros. Not quite the same problem as the author's, but the tools and scripts I've been using can do similar things :)
