A tip for both collectors and for eBay sellers - when I worked in bookstore management, we called these books "Junior League style" cookbooks because they are similar in format to the popular Junior League cookbooks. These books sell really well on eBay, whether Junior League, church group, regional restaurant, etc. ... and the recipes seem to always be wonderful! I have a very small collection of these cookbooks myself, from my hometown, and from restaurants I have really enjoyed eating at over the years.
Here is a little peek at a few of the cookbooks you'll find in my store online: http://search.stores.ebay.com/Birdhouse-Books_cookbook-cook-book-193-194-195-196-197_W0QQfcdZ2QQfciZQ2d1QQfclZ3QQfromZR10QQfsnZBirdhouseQ20BooksQQfsooZ1QQfsopZ1QQsascsZ0QQsaselZ81052548QQsatitleZQ28cookbookQ2ccookQ20bookQ29Q20Q28193Q2aQ2c194Q2aQ2c195Q2aQ2c196Q2aQ2c197Q2aQ29QQsofpZ0
