The Astronomical journal
A scientific periodical of astronomy, founded 1849 in the United States and published over decades by the Dudley Observatory and later the American Astronomical Society and American Institute of Physics, written for professional astronomers; the scanned run comes from the University of Toronto's Gerstein library. The plates are stacked line graphs of observational data drawn on fine printed grids, with Greek-letter axis labels and numbered scales, plus title-page type and a violet oval library datestamp.
