The LITA/ALCTS Electronic Resources Management Interest Group has established a mailing list (lita-erm@ala.org).
Here is a description of the IG from its home page:
Established in 2005. The purpose of the LITA/ALCTS Electronic Resources Management Interest Group is to promote and enable the exchange of information and discussion among librarians, publishers, electronic resource management system vendors and related service organizations concerning issues related to the management of electronic resources. The group will assist in developing appropriate and responsive systems and standards by fostering open and collaborative discussions and implementation issues.
