Also, I would higly recommend experimental poet Kenneth Goldsmith's [1] book "Uncreative Writing: Managing Language in the Digital Age" for those struggling with writer's block. In the context of this discussion one could say that his entire art deals with issues of writer's block very closely (e.g. he has "Soliloquy", a 800-page book consisting of every word he spoke during a week, etc).
A passage from "Uncreative Writing":
"There’s one solution that each and every book on writer’s block offers: write five words. Any five words. Follow this advice, Mr. Ashbery, and you’ll never have writer’s block again."

Edit: Oh, this historical paper is slightly different angle, but also relevant, helped me quite a bit:
