The role of the ACS Library and Information Center (previously, ACS Library Services) has dramatically changed. In addition to performing all typical library duties, the ACS Library is now offering many new services. These include a New Digital Imaging Center; publishing the ACS newsletter; staff training; serving the public through the Chem. Health & Safety Referral Service; providing a content-rich chem. information on the ACS Web page (http://www.acs.org/infocenter.html); and participating in the speakers service for local ACS sections. The challenges of imposing a new model to a traditional special library - and of making it work - will be discussed.
