Query: Kindle version is a challenge...

I haven't looked at the print version, but the Kindle version is challenging. The titles are arranged alphebetically. You have to "next page" quite a bit to find what you're looking for. If you want to use the search function to find a title it's hit or miss. For example searching for the title "Them" turns up over 400 hits. But searching for the title "Trog" gave 1 correct hit.
