Writes Bill Milligan, about "dangerous" and fun books for boys: "'The Golden Book of Chemistry Experiments' has a fascinating story behind it. Apparently it was pulled from bookstores and libraries in the 1960s by our very own gummint. Parents were convinced by busybody librarians to quietly confiscate and destroy private copies of what some commentators called the favorite books of their childhood.
"But the best part of the story is that due to a copyright lapse, the book lives in public domain. I discovered this book free online a couple of weeks ago."
