Backlog Information: As of April 30, 2012, the backlog for this journal was approximately 0 issues. This estimate is the result of dividing the number of manuscripts for this journal in the Providence office that have not yet gone to the printer on the above date by the average number of articles per issue over the previous twelve months, reduced by the number of issues published in four months (the time necessary for editing and composing a typical issue). In an effort to make articles available as quickly as possible, articles are posted to the AMS website individually after proof is returned from authors and before appearing in an issue.

Offprint information Offprints are provided free of charge in electronic form to all authors. A downloadable and printable PDF version of each article is available from the AMS website following print publication. Notification email containing access information is sent to all authors as soon as an issue is published in print. This electronic delivery system provides authors with permanent electronic access to their published material.

Inquiries: Any inquiries concerning a paper that has been accepted for publication that cannot be answered via the manuscript tracking system should be sent by email or by postal mail to the Electronic PrePress Department, American Mathematical Society, 201 Charles Street, Providence, RI 02904-2294 USA.
