If I post these on paperbackswap do you think people would want them?  I have a couple of Pampered Chef cookbooks in excellent condition.  No food stains or anything.  They don't have ISBN numbers.  I also have some church cookbooks.  If I posted these without the ISBN number how would people know that these books are available and on my shelf? 

They've often been the first to go off my shelf. I have a boxful now, and will be posting them soon. I guarantee you, they will fly off my shelf. People like to see what others have learned to create with their own utensils and in their own kitchens. You'll be surprised!

I'm partial to community / church cookbooks. Please DO post them.  Worst case scenario is that no one wants them and you have to remove them from your bookshelf and donate to charity...

Many of the Pampered Chef cookbooks WITHOUT ISBN's are considered pamphlets because they are less than 50 pages and are therefore unpostable.
