These sales figures are way beyond the range of even the most acclaimed fiction  Some of the books, such as "The Old Farmer's Almanac" and Emily Post's "Etiquette in Society, in Business, in Politics, and at Home," which was first published in 1922, are continually updated and reissued, and still maintain market share.  McHugh says that "Etiquette" used to be the second-most stolen book from the library after the Bible  which presumably is taken by people unfamiliar with the Ten Commandments). 

COMMENT 

Perhaps it's a stretch to say that stealing books is a use for libraries, but theft of library books is pretty frequently mentioned in library stories. However, it's not clear whether or not Jess McHugh (author of "Americanon") fact-checked this claim since online sources say that after the Bible it's the Guinness Book of World Records and books about conspiracy theories and the occult.  At one college library where I worked we deliberately left the magnetic anti-theft strip out of copies of a guide about sexual wellness and replaced it as needed. 

I'm not sure how to categorize this one.  Maybe "Life Changing Book"?
