Library are considering taking their fight to the Ombudsman.
Northamptonshire CC has agreed to move the facility from Caroline Chisholm School into Wootton Community Centre on a temporary basis.
It is negotiating to buy its way out of a contract as it is currently paying £150,000 per year.
But Chairman of the governors and a member of the Friends of Wootton Library, David Atkinson, said: “We are looking at possibly making a complaint to the council and possibly taking it to the Ombudsman.”
A council spokeswoman said the school has until July 31 to put forward an alternative.
