museumUpdated: The National Liberty Museum in Philadelphia wants to hear from firms to guide marketing and communications as it looks to build a national audience.

The museum, founded by publishing magnate Irvin Borowsky in 2000, wants to reach opinion leaders, teachers, parents and the general public, pitching the institution as a "national thought leader on liberty." It wants to boost both visits to the facility, as well as online traffic to its educational resources developed under a grant by the John Templeton Foundation.

An agency will be expected to develop a 21-month campaign slated to begin in June.

Proposals are due May 16. The due date has been extended until May 28.
