Information for Contributors.

The article presents information that manuscripts for publication and Letters to the Editor should be submitted to the Editor either directly or to one of the Associate Editors. Submission of a manuscript is a representation that the paper has been neither published nor submitted for publication elsewhere and that, if the work is officially sponsored, it has been released for open publication. The manuscript should be accompanied by a Copyright Transfer Agreement from the authors (or their employers--whoever holds the copyright) transferring the copyright to Operations Research Society of America (ORSA). The form for this agreement is printed in the journal "Transportation Science," and is also available from the Editor and the Business Manager. This written transfer of copyright, which previously was assumed to be implicit in the act of submitting a manuscript, is now necessary under Copyright Law in order for ORSA to continue disseminating research results as widely as possible. Copies of a manuscript will not be returned to an author unless he makes a specific request, or unless reviewers have provided annotations that will be of use to him.
