Not a book, but my November/December 1990 issue of View Camera Magazine got pretty pretty beat up…perhaps a chemical stain or two.
It contained an article describing how to make carbon prints. I would have it open next to me at each step of the process. I’d give it a go, fail, reread the article and go, “Oh, I missed that part.” or find that I had interpreted something wrong.
After months of failures and other learning experiences, I finally hand copied the instructions to save the magazine.
