There are book socks that one can purchase to cover textbooks. These are made from stretchy material, and they fit most hard cover books. Book socks don’t work well on paperbacks.
When I worked in a label factory, we had huge sheets of paper with beer or ketchup labels printed on them. Those co-workers who had kids in school would would take several sheets home, cut them up and make wrappers for school books. The kids loved them, and wanted more of them for friends.
I read over a hundred books a year, but I don’t wrap my books. In fact, I unwrap some of them. If I have to carry a book around in my purse to read in restaurants, I take the sleeve off the book and tuck the sleeve in a safe place at home until I finish the book.
I like paperbacks. They take up less room on the shelf and they don’t have sleeves. I could never understand why wrapping a book up was so popular. How do you know which textbook is which if you cover the book with paper? In college I never saw a book wrapped up, and college students do make use of their books. At least they do if they want to stay in college and graduate.
I do think see-through plastic wraps are an improvement. If you have to wrap up a book, at least wrap it up in see-through plastic, so you can still see the title.
Place the book in a plastic grocery store store bag if you think it will rain.
I looked up book socks on Amazon and eBay. They are not called book socks, but book covers. I like calling them socks better. The book covers that I saw don’t come in see-through. I guess if you want see-through covers buy a box of plastic wrap, the kind used for putting leftovers away in the refrigerator.
One could get creative. Have a soccer ball or football cover for the book in a health class. A Shakespeare cover for an English class textbook.
Which ones would I buy if I bought a book sock? I wouldn’t buy one. I like to be more intimate with my books. I like them bare. After all we are having a meeting of the minds. You can’t put a sock on that.
