Now on the Ohrstrom Library site is a new research guide in support of the Physics Firsts students investigating the sustainability of humans living in space. Spotlight on: The  4-volume Reference set,  2012 ed. of Space Sciences living within the Library’s digital reference collection. Research guides gather together the most pertinent library resources for a specific project, from the larger (and ever-expanding) universe of Library sources/collections. Please feel free to contact Ms. Sanborn (lsanborn at sps dot edu) for a research consultation and/or to discuss any of the items in this guide.
