A care service in Crowland that has answered more than 95 calls for help since April is concerned it may have to move again should the library where it is based reduce its opening hours.
Crowland Cares has been based at the library in Hall Street for the past five years, manning the desk each morning five days a week.
Last week, Lincolnshire County Council announced it is considering slashing libraries under its control from 47 to 15 in a bid to save £2million.
Libraries in Crowland and Long Sutton are not expected to be closed, but it is not clear what their opening hours will be.
Volunteer Philip Jackson said: “We want to know what is happening because it’s all very confusing.
“A lot of people are concerned – not just us. As I’m speaking to you, the Health Walks group is coming in.
“The library is also their base and there are a lot of groups who use it. Where are we supposed to go?”
The council has said that libraries under threat could only stay open if they are run by volunteers or are taken on by a business.
Mr Jackson said: “If it wasn’t for us I don’t think the library in Crowland would be open as much as it now.”
A 90-day consultation on the proposals is expected to start on Wednesday, July 3.
Spalding Library is safe and a glimmer of hope has now been given to all those under threat, including Market Deeping and Holbeach.
Yesterday (Wednesday), Lincolnshire County Council’s community and public safety committee recommended scrapping plans to close the libraries.
The executive will make the final decision as to whether to go out to consultation at a meeting on Tuesday.
County councillor for Deeping St James Phil Dilks said: “We have won the first battle to save Deepings Library but we will have to wait and see what happens when the executive meet.
“I spoke at the scrutiny meeting and there was clearly real concern these proposals weren’t the way forward.”
Deeping St James parish councillor Andrew Boswell has already set up a petition to save Deepings Library from closure and a public meeting has been planned for July 11.
