How many fanfics are their?
right between ao3 and fanfiction.net thats already around 1.3 million unique works, but that doesn’t include massive non-English archives like Russia’s Ficbook and Fanfics.me, Italy’s EFP, the dozens of segmented French HP-specific archives, Chinese webnovel platforms,The japanese sites i know exist but can never find, Wattpad, LiveJournal communities, private forums, tiny fansites and thats all before the stuff we lost over the years like everything on GeoCities and Angelfire. I've done some ball park math and as far as i can tell their is at least 8 million unique fics, and in the order magnitute of tens of millions of publicly posted works though not all of those are neccersarilly fics.
There’s a real argument that Harry Potter is the single largest unified fictional writing project in human history.
and i am slightly scared of how big this thing is that i've had to double check. its also a shame for most of us we will all barely scratch the surface
