Kerouac was something of a stream-of-consciousness writer in the style of James Joyce. So, when he wrote the book On the Road, he just put a sheet of paper into the typewriter and started typing. No paragraphs, no margins. When he came to the end of the paper, he taped a new sheet onto the end. He ended up with a 600-ft-long "scroll" on which the manuscript was typed (and it was over a short period of time too). The library is showing the first 300 ft now and will show the second 300 ft beginning in mid-February.
Okay, since I am still sitting in my office, I have missed seeing the scroll today. Guess I'll just have to give myself a different Valentine's present!!
