A lot has changed because of computers, including the interaction between writer and paper. Eudora Welty kept scissors handy in order to literally cut and paste sections from her work in progress. If she didn't like something, snip and it was gone. If it belonged in another paragraph, she would use pins to attach the clip.
Jack Kerouac wrote On The Road on sheets of paper taped together end to end as a long scroll. When the publisher said it would have to be cut up to be edited, Kerouac stormed out of the office in a rage. It was several years before his agent could find him another publisher for the book. Edgar Allen Poe attached final drafts to the original scrolls with wax, and Wallace Stevens wrote poetry on slips of paper while walking. He would later give them to a secretary to type onto regular sheets of paper.
James Joyce wrote while lying on his stomach, Virginia Woolf wrote standing up so as not to be outdone by her artist sister who also worked on her feet. Jack London could write 1,000 words a day compared to 3,000 words a day by writers like William Golding and Norman Mailer. James Joyce considered two full sentences as adequate output for a day, and Dorothy Parker once said that if she wrote five words she would have to change seven.
