+Description:
+    This catalogue was created based on the original published catalogue
+    by Barnard E.E., 1927, Carnegie Institution of Washington,
+    "A photographic Atlas of selected regions of the Milky Way".
+    The catalogue contains positions of 349 Barnard Objects.
+
+    The objects with numbers from 1 to 175 are classified in the first
+    Barnard catalogue (1919ApJ....49....1B); three of the objects in that
+    list have been omitted here (Nos 52, 131a, and 172) because these
+    objects had been listed twice.
+
+    The objects from Barnard's second list are numbered from 201 to 370 --
+    there are therefore no objects having the numbers from 176 to 200.
+    Their positions were determined by Miss Calvert.
+
+    The epoch for all positions in the original published catalogue was
+    1875.0. Positions for both 1875.0 and 2000.0, the diameters and the
+    notes are included in this machine-readable catalogue.

+Historical Notes:
+  * 25-Jun-1999: This catalogue was created by Junko Takahashi and Masatoshi
+    Ohishi at the Astronomical Data Analysis Center, National Astronomical
+    Observatory of Japan, based on the original published catalogue by
+    Barnard E.E., 1927, Carnegie Institution of Washington,
+    "A photographic Atlas of selected regions of the Milky Way."
+  * 24-Jan-2001: The diameters and notes were kindly supplied by Bill Gray
+    from the Pluto project (pluto@projectpluto.com)
+  * 30-Jun-2008: Thanks to Mati Morel, 6 position errors in J2000 positions
+    were corrected for the pairs B67/67a, B83/83a, and B117/B117a
+
+Acknowledgments:
+    Takahashi and Ohishi are grateful to Dr. Mitsuru Soma and
+    Prof. Shiro Nishimura for their codes for the coordinate conversion.
+    They also wish to thank all members at the Astronomical Data Center,
+    National Astronomical Observatory of Japan for their cooperation.
