That's by Scott F. Johnson and it's on his Academia.edu site:
The explosion of free PDFs of scholarship published before 1922 facilitatedby Google Books as well as Archive.org has had a strange, perhapsunexpected, effect on the nature of brand new scholarship that is fully under copyright. It has fostered the tendency among students and scholars alike, at least in the Humanities, to assume that if a book or articleis not online and not freely available then it is not published at all.
Many will be quick to guffaw at this statement but I increasinglyexperience its truth in the academic world.
I've not yet read the piece, but I'm biased in favor of the idea. FWIW, ever since my undergraduate years at Johns Hopkins I've been listening to senior scholars complain about how the publication system is now broken. Now, of course, I AM a senior scholar, and I publish to the web.
