DIY History now has the Hevelin Fanzine Collection open for crowd-sourced transcription. Doing the tables-of-contents and artist names for each issue would probably be the best initial route into this. I’d suggest that’s a do-able goal that could be crowdfunded for and then outsourced to paid Web-workers (on Fiverr, Mechanical Turk, etc), rather than taking up the time of someone better suited to more advanced tasks.
