Many libraries are part of networks, consortia, or regional system. And even for the independent libraries, there are still state libraries and state and national library associations that can provide guidance or support to the librarians in the trenches.
Recently, two projects were launched to benefit librarians at a local level, and both projects were started by a support organization.
Massachusetts Library License Plates
The Central Massachusetts Regional Library System (CMRLS) is working with the MA Registry of Motor Vehicles to make a "Massachusetts Libraries" license plate available to the public. Details (and a promotional bookmark [pdf]) are available on the CMRLS website, and funds raised from the sale of these plates will be returned to libraries through a grant process. This is a neat idea, but so far only has a few mentions.
Job Descriptions Database from the Maine State Library
The Maine State Library launched a centralized job description database, to aid librarians in defining the roles within their libraries. This is one of those tasks that we all share, so creating a central clearinghouse for descriptions makes a lot of sense - and keeps us from reinventing the wheel. Job descriptions in the database were all submitted by Maine libraries, and hopefully include my favorite line for a library staff job description, "other duties to aid patron access to information as assigned."
