Electronic Publishing at Astrophysical Journal Letters A. Dalgarno, Letters Editor, E. Avrett, Deputy Letters Editor The ApJ Letters Office currently receives a small fraction of new papers electronically, but paper copies of such submissions are sent to referees, by express mail or sometimes by fax, since most papers contain figures and other material that are not easily handled in computer readable form. Once a paper has been refereed, revised, and accepted, faster publication will be possible if the Press is sent the electronic file along with the printed paper to avoid typesetting by hand. The AASTeX macro program should be used for this purpose. ApJ Letters now maintains an on-line file of the abstracts of all Letters that have been accepted but not published. (See the inside back cover of the Letters.) We hope that in the future it will be possible to include full articles in such a file so that a Letter could be available electronically in advance of the printed version. The Letters Office has asked that the AASTeX macro program include a formatting option that could allow authors to see approximately how their paper would appear in the ApJ two-column page layout. This could help authors determine whether they can lengthen their paper or would have to shorten it to stay within the limit of four journal pages.
