It looks like Oracle is using Texterity, a provider of services for the creation of digital editions of magazines, to publish Oracle Magazine in a digital format over the Web, more precisely in the Published Web Format (PWF).
I have not read or heard of an official announcement from Oracle about Oracle Magazine now being available in PWF. This must have started recently, judging from the archives available in this format which goes back only to the July-August 2006 issue of the magazine.
Check it out at www.oraclemagazine-digital.com/, but be aware that the web site is not Firefox friendly. The navigation links such as Contents, Search, Archives and others work only in Internet Explorer.
