The following is from IAU Circular 4168
CATALOGUE OF COMETARY ORBITS
The fifth edition of the 'Catalogue of Cometary Orbits', a
joint publication of the Central Bureau for Astronomical
Telegrams and Minor Planet Center, is now available. The
102-page book, which is in the same general form as the 1982
edition, contains 1187 sets of orbital elements calculated up to
the end of 1985 Dec. Subscribers to these Circulars may purchase
the new edition for $6.00 (half the cost to nonsubscribers), and
arrangements can be made to debit a subscription account
accordingly. The basic part of the catalogue (including a direct
reference to the comet names) can also be purchased in the form
of seven ASCII files on a diskette; the diskette also contains
(compiled) computer programs to extract specific orbits from the
catalogue and to generate ephemerides, either from such orbits or
from similar user-prepared data. The diskette is being issued in
IBM-PC DOS 2.0 double-sided double-density format (and it should
be noted that the computer programs require an 8087 mathematical
coprocessor) for $100.00 or in VAX/VMS format (either 8-inch or
5.25 inch, double-density) for $150.00. A magnetic-tape version
(without programs) costs $250.00.
