Forgot to say - this is original by me; guess I oughta copyright it too. Thanx! -Cliff Stoll Ever notice that the second or third time you read a book, you discover all sorts of typos and misprints? The more often you read a book, the more typos you find. These typos are read-errors; mistakes introduced by reading the text. To preserve accuracy, you should purchase a new edition each time you wish to read a book. Most of all, avoid used books, pirated editions, and books from unknown sources. Public libraries are especially dangerous! Library books are read many times, introducing uncounted read-errors. Worse, borrowers (and some unscrupulous authors) can infect books with literary viruses (analogous to computer viruses) which can be transmitted to other readers. You can avoid these problems by only reading from new books, and purchasing fresh shrinkwrapped volumes at your local bookstore. Hardback editions are most resistant to typos and literary viruses; get these whenever possible. A public service message brought to you by a disinterested party -Cliff Stoll cliff@cfa.harvard.edu
