Barnard’s Stars

Edward Emerson Barnard’s posthumous 1927 work, A Photographic Atlas of Selected Regions of the Milky Way, has been digitized in its entirety and put on the web by Georgia Tech; here is the web site. Browsable by region and searchable; both photographic plates and charts (at right, the Pleiades) are available in surprisingly large resolutions. Via Plep.
