Information for Authors
Submissions must be sent electonically in either .pdf or .ps format
and should be sent to the Managing Editor.
It is understood that the contents of the paper have not been published elsewhere,
and will not be published elsewhere. The author should retain a copy of the paper.
The Editorial Board cannot accept responsibility for the return of submissions.
In preparing the manuscript, avoid compositors' conventions, such as coloured underlining.
Text need merely be typed in Roman letters, according to the standards of the AMS. Tables
and figures should be numbered and in a form suitable for photographic reproduction. References should be given in the form
[1] to a final alphabetically organized list of references, which should include page
numbers. Authors' names should not be inverted in the reference list; write C.T. Onions,
not Onions, C.T.
Once a paper has been accepted, send a .pdf or .ps file to the Managing Editor.
The file must be in 10 point Times or Computer Modern font, single spaced, with the text
being 4.5 by 7.125 inches (11.4 by 181.0 cm).
We use your copy as camera-ready. An invoice for 25 reprints (with or without covers) will be sent
to you if you ask for the reprints.

Priority Publication Page Charges
Our policy of voluntary page charges operates as follows. If you do pay page charges, your paper
will receive priority publication. It will go to the head of the queue and will appear in
the next issue of the journal that goes to press (this could cut as much as a year off the waiting time).
This policy will not cause any delay for papers already in the queue, since all priority publication
articles will result in additional pages in the journal. For example, if there are 64 pages
of priority-paid articles for an issue, that issue will contain the regular number of pages,
plus an additional 64 pages. In this way we shall be able to publish larger volumes of
the journal. Authors who are not able to pay page charges will also benefit considerably, since
the priority articles will be removed from the queue and thus the queue will be shortened.
The US Postal Service has recently increased its charges a great deal.
Effective January 1, 2010 the priority page charge will be
US$50.00 per page if paying by cheque; US$54.00 per page if paying by VISA or bank transfer.
