PASA presents PASA Letters for the rapid publication of high impact original research that merits a quick turnaround. Manuscripts submitted for publication in PASA Letters should be prepared in the usual way (we recommend the Overleaf template) and meet the usual criteria for articles published in PASA. In addition, the work reported is expected to be timely and have high significance or influence on the development of other research in the area. Letters should be self-contained and are limited to 5 pages, but can have supporting appendices. At the discretion of the Editor in Chief, in exceptional circumstances, PASA Letters will accept longer submissions. Letters are processed on a fast track, a referee’s report is expected in about 14 days, and authors are expected to respond in a similar time. Authors are required to state their reason for seeking publication in the form of a Letter in their cover letter. If in doubt, please contact the Editor in Chief prior to submission.
