Two distribution lists are available specifically for astronomy librarians to share relevant information on widely varying subjects. Astrolib (started in 1988) with ~ 200 members is managed by E.Bouton (email@example.com), librarian at the National Radio Astronomy Observatory (NRAO). The European Group of Astronomy Librarians (EGAL), is managed by I.Howard (firstname.lastname@example.org), librarian at the Royal Greenwich Observatory (RGO). J.Regan (email@example.com) is currently trying to set up a group in Asia and the Pacific Rim. People wishing to post announcements to libraries including physics and mathematics departments should get in touch with the moderator of the email distribution list of PAMnet, a network of Physics, Astronomy and Mathematics librarians. Send your inquiry to firstname.lastname@example.org.
U.Grothkopf, ESO librarian, maintains a list of names, addresses, phone and fax numbers, email address and homepage URLs of astronomy librarians and libraries world-wide. A useful search engine (www.eso.org/libraries/astro-addresses.html) can find librarians even from incomplete information. Librarians not on the list are encouraged to send information to email@example.com.
