"Elsevier is liberal with respect to authors and electronic preprints. Unlike some publishers, we do not consider that a preprint of an article (including a prior version as a thesis) prior to its submission to Elsevier for consideration amounts to prior publication, which would disqualify the work from consideration for re-publication in a journal. We also do not require authors to remove electronic preprints from publicly accessible servers (including the author's own home page) once an article has been accepted for publication."
