More than 500 people visited Adlington Library on Saturday to call for it to be kept open.
As Lancashire County Council looks to close 40 of its 74 libraries amid funding cuts, a group has been set up to protect Adlington Library.
People signed a petition, waved placards and spent time using the library on Railway Road on Saturday.
Among those in attendance were pupils from Adlington Primary School, who produced “save our library” posters and sent a letter of support. Borough councillors June Molyneaux, Kim Snape and Peter Wilson were also there.
Organiser Stuart Clewlow said: “Absolutely overwhelmed by the response and if any motivation was needed it came in the form of over 500 residents turning up to sign the petition and show their support. Councillors, youth organisations, school children, local businesses, local authors, residents young and old, people from a large cross-section of the community made their opinions known.”
A similar event will be held at Euxton Library from 9.30am to 12.30pm on Saturday, while the campaigners at Coppull Library are organising book walks on Saturday, March 12.
