Want to help the greatest library around? In the February 4, 2008 issue of Newsweek magazine, page 4, there is a little blurb about a Library of Congress pilot project. The Library has teamed up with Flickr Commons, featuring several thousand of the library's archival photographs. The hope is that people will help tag them in order to provide collective data. Collections include "1930s-40s in Color," and "News in the 1910s."
"These beautiful, historic pictures from the Library represent materials for which the Library is not the intellectual property owner. Flickr is working with the Library of Congress to provide an appropriate statement for these materials."
