Walsall Council has revealed plans to cut the libraries in the borough from 16 to one in a bid to help make £86m worth of savings, the BBC has reported.
The council will need to make the savings by the end of the 2019-20 financial year.
The authority, a Labour-Liberal Democrat coalition, said it had to "look at everything... on the table".
Earlier this year, The Bookseller reported that Walsall Council had earmarked seven libraries for closure – Beechdale, Blakenall, New Invention, Pleck, Rushall, South Walsall and Walsall Wood.
The new proposals would see all branches in the borough close, with only the Central Library in Lichfield Street staying open.
