Don’t worry if you don’t have the funds for a hardback copy, or if it’s out of stock. The most important thing is that you’ve chosen a good book for your loved one to enjoy!
Trade paperbacks will sometimes be released in a hardback-style height, so check the measurements of your shelf and your other books before you completely rule out a paperback. If the height matches, you can save a couple dollars while maintaining the even line of your bookshelf.
