Recommended abbreviations for frequently used terms are listed below along with some common misuse.
et al. The use of et al. (no comma before et) is encouraged in the body of the paper, but discouraged in the references. The names of all authors should be given in the references, unless the number of authors is greater than ten.
(in press) means that the paper has been accepted for publication in a journal (or a conference proceedings). The name of the journal must be specified. If the paper has been published when the author receives the proofs, the reference should be updated in proof.
(submitted or to be submitted) means that the paper has been submitted or will shortly be submitted for publication. The name of the journal, book, or conference proceedings must be specified.
(unpublished) means that the information is unavailable in printed form. Ph.D. theses need not be marked (unpublished), since copies can be purchased.
Conference Proceedings. Name, place, and year of the conference should be specified. Specify the editors and publisher if possible. Give page number.
Preprints and Reports (electronic or hard copy). Give name of laboratory, preprint or report number, and year. Give the title if possible and especially if a preprint or report number is not available.
Books. Give publisher, year, page number.
Journal references. Phys. Rev. C 20, 195 (1979). Nucl. Phys. A249, 253 (1978). (Note difference.) For Annals of Physics use Ann. Phys. (N.Y.).
(private communication) means that the information is not available either in published or report form and acknowledges the receipt of information from another source. References to private communications in which the name of one of the authors appears are not acceptable.
References to papers published in peer-reviewed journals are considered primary references. References to e-print archives should not be used in place of primary references.
It is important to confirm the accuracy of bibliographic information in references. This has become more important now that the journal is online; establishing functional hyperlinks from reference lists to bibliographic and document databases depends on the accuracy of the data contained in the anchor reference. Since at the present time such links work only from the reference section, work cited anywhere in the paper, including in figure and table captions and in ``Note(s) added,'' should be included in the reference section.
