I picked up Good Blonde by Jack Kerouac a few weeks ago at Recycled Books in Denton. I've read most of Kerouac's stuff so this was one of the few extraneous works I had not come across before. This collection came out in the early 90's and contains miscellaneous essays, magazine interviews and some random stories that Kerouac wrote over the years.
I had seen some of these essays here and there online (like Kerouac's Rules for Writing) but most of this was new to me. Much of it was great. Other parts...kinda meh. So an uneven collection of writings overall. If you like Kerouac I recommend checking it out. But for the casual reader...you might stick to On the Road or The Dharma Bums.
