Sutton Coldfield councillors will be asked to stump up £150,000 to keep the town's threatened library open.
The library, based in the Red Rose Shopping Centre , is one of the city's most expensive to run and has been earmarked for closure by Birmingham City Council as a cost-cutting measure.
More than 6,500 names have been put to petitions calling for a library to be retained - even if it has to relocate to a smaller, more moderately priced building. The Royal Sutton Coldfield Town Council was formed last March and this is its first major challenge.
It is to debate a motion calling for it to use its own money to keep the service afloat on January 24.
It has been tabled by independent councillor Liz Parry (Vesey) and states: "This council has previously expressed support for the retention of a modernised library service within Sutton Coldfield town centre.
"Neither a location nor funding have yet been secured.
"This council therefore resolves to allocate £150,000 from the unallocated portion of its 2016/17 budget, to use if necessary to support the continued provision of a library service in the town centre after April 1, 2017, in order to enable a long-term solution to be finalised."
But the Conservatives, who dominate the council, are likely to propose an amendment - particularly as they do not believe the town council should be paying for core services like libraries.
The town council was set up to provide top-up services and raises its funds through a premium on the council tax.
Conservative councillor Ewan Mackey (Trinity) said: "We are behind the spirit of the motion, we are all fighting to keep the library service in the town centre. "But, as it stands, the motion will not solve the problem. "Birmingham has the legal duty to provide the library service.
"Sutton residents pay their council tax to Birmingham and are entitled to receive that service."
The town council has been given until January 27 to come up with a rescue plan. The city council is currently consulting over a £1.95 million funding cut to city libraries which includes the closure of the Sutton Coldfield and Aston branches as well as reduced opening hours elsewhere.
