I am a collection development librarian on Long Island. Two years ago I had a thyroid operation which resulted in my going Paleo. Since I didn't know anything about Paleo, I went to the library catalogue and was surprised to see the stats on any book about the paleo/primal lifestyle. Even though there were very few books, they were all out and had circulated many many times. I thought that this was a good new category to develop and, in the last two years have purchased 12 nutrition/cookbooks for the collection. I now have so many that I thought it would be helpful to label them "paleo" under their dewey number, as we do for our "gluten-free books." When I went to the catalogue yesterday to collect the books for relabeling much to my amazement-every one of them was out. I went to a Simon and Schuster book presentation last week and they were pitching a new book for women, as Paleo is "a guy thing." This book is entitled "Paleoista," and is reaching for the chick-lit audience. I guess we've "arrived" now. BTW if anyone wants a list of the books I ordered, would be happy to print them.
