CD‐ROM: an overview of US developments

CD‐ROM technology, introduced to librarians in the US four years ago, has taken hold as a support tool for technical processing and public services activities. In the interim, librarians and vendors have worked together to improve services and systems and develop new products in response to user needs. Further developments will depend upon librarian initiatives, vendor efforts to exploit other types of optical technologies to full advantage, and the development of standards that will assure uniform quality and acceptance.
