Union List of Astronomy Serials
The Union List of Astronomy Serials (ULAS), 2nd edition, is composed of bibliographic information for (primarily) non-commercial publications of observatories and institutions concerned with research in astronomy. To each of the approximately 2300 titles included are appended the holding records of 42 contributing libraries, representing the most comprehensive astronomical collections in North America, with selected holdings from China, Europe, India, and South America as well. ULAS is an on-going project of the Physics-Astronomy-Mathematics Division of the Special Libraries Association. Judy Bausch of the Yerkes Observatory is the coordinator/compiler.
