Lunar and Planetary Institute limited collection development extending into the secondary support field of computer science remote sensing. There is an ongoing effort to scan and make available to the scientific community and the general public a number of out-of-print planetary science books, NASA documents and images, and related works. (These publications are copyright-free or made available with permission.) This collection is a NASA Regional Planetary Image Facility (RPIF) and includes photographs, maps, and other data from planetary missions including Apollo, Lunar Orbiter, Clementine, Mars Pathfinder, Voyager 1, Voyager 2, Magellan, Galileo and Mars Global Surveyor. The library maintains a weblog called What's New
