Yes, but what if you aren't a national depository, have very limited funds, and must therefore choose?

"As a national depository, Cambridge University Library was entitled to a copy of every book published. Nevertheless, it disdained to collect items deemed beneath its dignity, and thereby refused books by Austen, Byron, Shelley, and Wordsworth."
