Jane Holmquist, the Astrophysics Librarian, will be demonstrating the Landolt-Bornstein Database, tomorrow, Friday morning, in Grand Central — as part of a trial that the University has from SpringerMaterials. She will answer any questions you may have in this second session of "Tool Time", a series featuring Library resources in astrophysics. (Group VI of L.B. is Astronomy and Astrophysics.)
