Volumes dedicated to a single topic have been released, under the title Uncle John Plunges Into..., for example: history, presidents, and the universe. There are also books on individual U.S. states, the weather, numbers, quotes, the year 2000, a special book for mothers, cat lovers, love, Uncle John's Book of the Dumb, and several Bathroom Readers for Kids Only!. Though most of the books were written by the Bathroom Readers' Institute, some of the ones that are based around a specific subject are written by a lone author, who is not in the Institute. Additionally, the Institute will often publish articles and other contributions sent in from readers. Recurring articles such as "Flubbed Headlines", "Oops", and "Classifieds" often depend on these contributions.
Their volumes contain information on subjects such as quotes, dumb criminals, palindromes, anagrams, urban legends and hoaxes, failed inventions, the history of everyday things, and accidental discoveries, as well as articles on pop culture and 'celebrities' such as Emperor Norton (see Features). Throughout the books, there are what the BRI calls "running feet" - short fun facts on the bottom of each page. A typical example is "An object on Jupiter would weigh 144,000 times more than it would on Pluto." Some books have one running foot that simply says "Hi, mom.", being the dedication.
