I have found that I am having to buy more and more Kindle books, as I can't find what I want here, in paperback.

Does anyone know if I can trade the Kindle books, instead of just deleting them from my tablet when I finish reading them?

You cannot swap them here or anywhere. You don't actually own a Kindle book, you just own a non-transferable license to use the software (the book) on your e-reader or computer.

Some Kindle books can be lent to another reader one time for 14 days. There are sites like booklending.com that will help you find borrowers for your books and find lenders for the books you want to read.

  Instead of buying them in the first place, have you tried finding them at the library? It's incredibly easy to borrow a kindle title from the library. I've used Kindle on my iPad for 3+ years and I think I've spent less than $10 on books since I get them from the library or free through pixel of ink, book bararian or bookbub, which link to free titles at Amazon. The newest titles are almost always WL here at PBS (regardless of genre) but are often available at some libraries immediately or after a short wait. Also check out the E-books forum here at PBS as there is quite a bit of good advice, including about libraries across the country that can be accessed (some free and some for a fee) if your local public library doesn't have a very good selection.

I am new to using E-Books, so didn't know much about them.

I have been using BookBub, and get free ones as often as I can.

I MUCH prefer paperback books, because they are easier for my painful hands to hold.

Laws are different for e-books, and it is not legal to transfer ownership.  Some Kindle books can be loaned once via Amazon, but otherwise libraries are the only other venders licensed to 'loan' e-books.

Other than the above, you cannot legally give, trade, or sell your e-books.
