Subscribing To The International Comet Quarterly

The ICQ is published in January, April, July and October of each year, with annual subscription rates currently being US$40.00 worldwide with surface-mail delivery outside North America, including the annual Comet Handbook (or US$30.00 without the Handbook). Subscribers who do not wish to be billed, and who will keep track of when their subscription expires, may subscribe at the special rate of US$30.00 worldwide (the special rate without the Handbook is US$20.00); a US$20.00 annual additional amount must be ADDED for airmail delivery for ALL subscriptions outside the United States for which airmail delivery is preferred over surface-mail delivery. The second set of digits on the top line of your mailing-address label states the last whole number which you are scheduled to receive under your current subscription status).

The annual ICQ Comet Handbook is available for US$10.00 to ICQ subscribers, and for US$15.00 to non-subscribers.

[Note: The above subscription rates reflect the first increase in rates in twelve years -- raised due to ever-increasing printing and postage costs. (August 31, 2005)]

The above subscription rates are valid until 2007 October 31 only. Payments remitted after 2007 October 1 will need to reflect the yet-again increased subscription rates: US$60.00 worldwide with surface-mail delivery outside North America, including the annual Comet Handbook (or US$45.00 without the Handbook). Subscribers who do not wish to be billed, and who will keep track of when their subscription expires, may subscribe after 2007 Oct. 1 at the special rate of US$45.00 worldwide (the new special rate without the Handbook will be US$30.00); a US$30.00 annual additional amount must be ADDED after 2007 Oct. 1 for airmail delivery for ALL subscriptions outside North America for which airmail delivery is preferred over surface-mail delivery. The annual ICQ Comet Handbook will be available after 2007 October 1 for US$15.00 to ICQ subscribers, and for US$25.00 to non-subscribers.

Note that, while money can be "wired" from one's bank account to the Smithsonian bank account for a subscription to the ICQ, one must add $20 extra in bank fees for this service (contact iausubs@cfa.harvard.edu for information on how to transfer monies between banks). Effective 2007 December, payment cannot be made by credit card, by decree from Harvard University; we are working to set up a new procedure to accept credit-card payments.

[Note that special subscribers who fail to renew on time must pay for missed back issues at the regular rate of US$10.00 each.] NOTE: Subscriptions can only be started with the current issue; all back issues are to be obtained from the Editor (address above) at the rate of US$10.00 each (back issues are available from No. 29 onwards, with a few exceptions; about 10 or 12 issues of The Comet and The Comet Quarterly dating back to 1975 January are also available on a first-come-first-served basis until stock is depleted). Group rates are available upon request. Periodical subscription companies and book dealers do not receive discounts. There are no refunds for unused portions of subscriptions in the event of cancellation; unused portions can be transferred to subscriptions to IAU Circulars or Minor Planet Circulars.

The ICQ also maintains a photometric archive of some 80,000 published comet observations; interested researchers should contact the Editor for more information.
