The committee created in the wake of the racially charged July 16 arrest of Harvard professor Henry Louis Gates Jr. is widening its scope, asking anyone who lives and works in Cambridge to join a subcommittee soliciting ways to improve relationships between government and citizens.

The group is asking people to comment at the Main Branch library Wednesday from 6:30 to 8:30 p.m. and Thursday from 11 a.m. to 1 p.m. The library is at 449 Broadway; the group — the formal name of which is the Cambridge Review Committee Community Subcommittee — is planning to meet in the branch’s lower lecture hall.

Jennifer Flagg, hired to facilitate the committee’s communications with the public, describes its work as:

Identifying “lessons learned” for the city, the police department and the nation; helping the city as a community engage in a meaningful dialogue that brings its neighborhoods closer together and breaks down communication barriers; and identifying opportunities for the city as a whole to learn and grow from this experience and serve as a national model of how to respond to a community incident.

As part of the Wednesday and Thursday meetings, citizens will be asked to say what else the committee should be thinking about.
