Circular Distribution Policy
The following policy statement applies to the distribution of the printed
and electronic forms of the
International Astronomical Union Circulars,
Minor Planet Electronic Circulars
and Minor Planet Circulars
(hereafter referred to generically as Circular):
- Under no circumstances should Circulars be posted to Usenet
newsgroups or general access bulletin boards. Limited extracts
(as defined by "fair use") of information from Circulars
may be posted as long as the source of the information is clearly
referenced. "Fair use" includes the occasional extraction of orbital elements
and/or ephemerides, but does not include the verbatim extraction of
large blocks of descriptive text. If in doubt, check!
- Astronomical societies and institutional subscribers may post the
Circulars to internal distribution lists or bulletin boards
as long as the society or institution has a
subscription and the distribution list
or bulletin board is restricted to members of the society or the
institution. For large institutions, such as universities, this means--for
example--the Astronomy Department only, not the whole university.
Large groups should consider taking out additional subscriptions for the
electronic versions of the IAUCs and MPECs at the suggested
rate of one subscription for every 20 readers.
- You are advised that Circulars provided here are for your
own personal use only and must not be redistributed (other than
as permitted above).
- The collection of Circulars in datasets and the indexing
thereof are permitted only for your personal use.
- Inclusion of Circulars in commercial products of any kind
without express written permission is strictly prohibited (even if you
are a subscriber).
- Information on subscribing to the
various Circulars is available.
