I buy and read a lot of books, scripts, and reports, and often keep my favorites prominently displayed on my bookshelves at home and at the office. It's the books I love the most that I'm most inclined to lend out, so I want to put my name and contact information in them. But writing my info in pen isn't great, because I may someday donate books to libraries or used bookstores, and I don't want my information in the book.
Buy a few sheets of removable address labels. A few minutes with my favorite word processor and I can print a whole sheet of my name and contact info. Then, when I buy a new book or script or receive an important report, I just label it using a removable label. If I loan it out, my info's still there. But if I decide to get rid of it, I can quickly peel off the label, keeping the book or report in pristine condition.
