The process to construct a new library began with a grant that the previous library director wrote several years ago.
She said Nauset Construction of Needham will build the $9 million facility which is expected to open in either December 2015 or January 2016.
The library board of trustees were awarded a construction grant from the Massachusetts Board of Library Commissioners for $4.3 million and the town matched the grant with $4.5 million.
Until then, Barry said they will have a temporary home in three trailers by the end of the month.
The modular trailers are being set up on Eastham Town Hall property. While those trailers are being set up, the library will continue with its regular hours on Samoset Road.
A groundbreaking ceremony for the new library is scheduled for Saturday, September 13 from 11 AM to 1 PM.
