Beginning April 3, 2000 corresponding authors for articles to be published in PRA, PRB, PRC, PRD, and PRE, who have an available e-mail address, will be able to access Acrobat pdf files of their composed article and copyedited manuscript via the World Wide Web. The authors will receive an e-mail message from our Production Department at The American Institute of Physics with instructions for retrieving the proofs and submitting corrections. If the proof material has not been downloaded after 7-10 calendar days standard proofs will be sent.
