Old almanac books have been sold for a year. What about the rest?

There are several ways to deal with it:

First, keep selling. Some people will buy books, even if they are out of date.

Second, as an antique collection. Can be well preserved, and then released for sale on the Internet after 20 or 30 years, as a collection of antique lovers.

Third, selling waste products

If it is really annoying to put it in your own warehouse, you can sell it as a waste book.
