One of my favorite blogs of late (many thanks to Slog for introducing us) is Awful Library Books, a blog dedicated to the process librarians go through to "weed" their bookshelves by removing books that aren't relevant or appropriate for modern library clientele. Two librarians in Michigan, Mary Kelly and Holly Hibner, decided to use their blog to highlight some of the wackiest books they (or other librarians) have found from weeding.
My personal favorite so far is undoubtedly The Betty Betz Party Book: The Teen-Age Guide to Social Success, published in 1947 (and, until recently, occupying library shelf space somewhere in the country). Betty provides advice on appropriate party clothes ("Always be sure that your dresses are at least an inch or so below the knee, because it's always embarrassing to have a few cards wisecracking about your peekaboo knees"), inviting guests ("If you have singles, be sure that they can be paired off suitably. And don't forget to consider such things as height, looks and IQ"), and throwing themed parties (including a butterfly chase party, during which previously paired couples get a butterfly net and small bottle of gasoline "to chloroform the insects.") That's some party, Betty.
Many of the weeds featured on Awful Library books, including Betty Betz, are available through Amazon's third-party Marketplace. So, if you want to know more about scarf arranging, turning your Atari into a keyboard organ, or how to be a reasonably thin teenage girl (really!), chances are you'll find the book you need at Amazon if it's been weeded from your local library.
