I have a box of old hardcover books (30 years old plus) many were printed in China or Taiwan so they don't have ISBNs.  Some examples are The Technique of Chineese Cooking,The Good Deed by Pearl S Buck, Tobacco Road by Caldwell...Do ya reckon anyone will be interested?  How does a person enter a book without an ISBN and unlikely to be in the system?

Don't know about interest. Here is the how/where:

There's plenty of interest in older editions as far as I can tell.  I'm a fan of vintage books, and might even browse your selection once you're done entering these titles.  Dappledart's sent you in the right direction (the page where you enter non-ISBN books) but in case you have any questions about the process in general, here's a few Help Center pages too:

How do I post a book without an ISBN?

Remember to include as much information about your books as possible.  The more information, the more likely your books will be requested.  When you list these books they'll be unique entries into the system, which can help your books move as well.  If you need help finding cover images send me a PM with a list of the titles in question and I'll see what I can do :)  Once you've got them listed, you can showcase your shelf in the Book Bazaar to advertise your vintage books.  You're bound to get a few requests that way.

Could these kinds of books be a type unto themselves within the system?  I personally do not collect books.  I understand that others do and there are people like me that might not appreciate what they have if and when they get one.  So couldn't a forum and/or category listing for vintage books be added?

Perhaps they can be tagged as vintage books.

I don't see what the confusion is...I have listed numerous pre-ISBN books, and a number of them have been ordered.  I've ordered quite a few myself for my collection.  Just choose "post a book without an ISBN" and fill in the information.  As long as they meet posting guidelines, and someone wants it, it doesn't matter how old it is.  The listing works exactly the same, you just can't search by ISBN, which I doubt most people do anyway. 

I do like the idea of somehow tagging, or catagorizing, or making more searchable the no ISBN books. Personally.

I dunno...but I want to Technique of Chinese cooking!

If you're posting w/o an ISBN--people will know it's old by the publication year. If they meet posting guidelines, don't worry about the no isbn or how old they are.  The binding and publishing year are on the listing. If someone wants a newer version then they need to order a different version.  Most likely if it's unavailable on PBS then whoever orders it won't care that it's 30yrs old and has no ISBN.  Also since PBS issued ISBN's are only supposed to be used for that one copy-you could tag the book with something like "printed in China-pre ISBN". 

The operative point being make sure they meet posting guidelines.  Otherwise, post away!

If you're doing a non-ISBN posting, including a cover photo can really help, too.

And cookbooks always fly out of here.

Cheers,
