  The new cometary catalogue containing data for almost 300 long-period comets
that were discovered before 2018 is announced (the CODE catalogue). This is the
first catalogue containing cometary orbits in five stages of their dynamical
evolution, covering three successive passages through the perihelion, except
the hyperbolic comets which are treated in a different manner. For about 100 of
these long-period comets, their non-gravitational orbits are given, and for a
comparison also their orbits obtained while neglecting the existence of
non-gravitational acceleration are included. For many of the presented comets
different orbital solutions, based on the alternative force models or various
subsets of positional data are additionally given. The preferred orbit is
always clearly indicated for each comet.
