Elsevier has consolidated their Harcourt eJournal into their newer platform which rolled out in October 2003. Elsevier's has effectively migrated all its websites to a single platform.
This single platform http://www.journals.elsevierhealth.com is for individuals and society members. (Please note: The platform migration is not related to, and has no impact on, access to ScienceDirect Elsevier journals.)

Some institutional customers who had online access to some of the journals on the former Harcourt platform can continue to access their entitled journals using the same username and password as they had previously. Unfortunately, as part of the platform integration, the URLs that institutions had used to access these journals have changed.

As I mentioned earlier the new single platform is intended for individuals and society members, Elsevier is currently developing a permanent solution to address the online needs of these institutional journal customers. While the old URLs appear to re-direct you to the new platform, institutional have some problems.

For example go to an article in the August issue of Gastrointestinal Endoscopy.
A prospective study comparing endoscopy and EUS in the evaluation of GI subepithelial masses. Hwang JH, Saunders MD, Rulyak SJ, Shaw S, Nietsch H, Kimmey MB pages 202-208

You are directed to a sign on page. Immediately your institutional users are going to try and sign on in the username and password field. However, in the right hand side box it says,

"NOTE TO INSTITUTIONAL SUBSCRIBERS: Institutions with subscriptions to Gastrointestinal Endoscopy should NOT log in or register at this site. Please visit and bookmark http://www2.us.elsevierhealth.com/inst/serve?retrieve=pii/&artType=pdf to access full-text journal articles. Contact Elsevier Customer Service with questions or concerns."

BUT when you click on the institutional link to access the full-text, you are directed to a page that says, "The requested media does not exist."
