While searching for information on Arthur Leff’s classic, “Swindling & Selling,” my hyperlink tracks led me to wikihow ( and How to Import Old Public Domain Books to wikihow) and to How to Draw a Monkey and then on to where I really planned to go, Stanford’s Copyright Renewal Database (an interview, by Mary Minow of Library Law, with the database’s founders can be found here).
Ain’t librarianship (and research) grand! Now, if only someone would reprint Leff’s Swindling and Selling. Sigh.
