If your browser has a FIND feature, search for =M27= to find M27, for example.

This file contains references in magazines and books to the Messier Objects.
The file is in Messier number order.  The top line for each object begins
with an equal sign followed by all names I know for this object. The
remaining lines are the references.  Someday I may provide a nicer interface
for this information, but here's what I've got so far.

Each magazine reference starts with
  A (Astronomy Magazine)
  S (Sky and Telescope Magazine)
  K (Deep Sky Magazine)
  R (Reflector)
  T (
followed by
  2-digit year
  1-digit month (x=October, y=November, z=December)
  page number(s)
  and sometimes some description of what's contained in this
    reference (p=picture, s=sketch, d=description, f=finder, t=theory)
  followed by a period.
