The Smithsonian Libraries' physical collections cover subjects ranging from Art to Zoology and everything in between - a diversity that reflects the research that goes on at the Smithsonian in our Museums, Zoological Park and Research Centers.
Most books available here are in the Public Domain unless otherwise noted, and are therefore free to download, use, re-use, and re-mix without regard to copyright. Due to the nature of library collections however, it can be difficult to determine copyright status.
