Plans to reduce opening hours at some West Sussex libraries and cut the mobile library service completely have been put out to public consultation.
As part of its efforts to save £75.5m over the next four year, the council plans to close Crawley, Chichester, Horsham and Worthing libraries from 6pm rather than the current 7pm from April 2020.
It also plans to drop its Horsham-based mobile library at the same time.
The Bognor-based service was taken off the road in June when its pre-MOT inspection showed it would cost more to make the vehicle roadworthy than it was actually worth.
The county council hopes to save £175,000 by making the changes and members of the public have until Wednesday November 13 to have their say.
The final decision will be taken later in November by Jacquie Russell, cabinet member for fire & rescue and communities.
She said: “Since becoming cabinet member, I have often been asked about what will happen to libraries across the county. As I have said before, we need to look at doing things in a more affordable way, but ultimately my aim is to preserve the core of the library service.
“With the suggested savings being proposed, we hope that the other services we have on offer at libraries across West Sussex will diminish any negative impact to users. However, I still want to hear the thoughts of our library users by way of this consultation, especially those who are specifically affected by the proposed budget savings, as this will help to shape and inform my decision in November.”
