In the face of these changes, academic librarians have no choice but to take action. Their challenge, though, is that there are simply too many print books and not enough on-campus space to store them.
The most obvious solution to too many books is “weeding,” the library profession’s term for removing books from a collection. While weeding creates space for new books, it has significant labor and disposal costs. Also, it can meet with stiff resistance from faculty and students.
So an increasingly popular strategy for managing overcrowded stacks is moving books to high-density, low-cost, off-campus storage.
