HighWire launches re-designed PNAS site on new H2O platform -

Stanford University' HighWire Press and the Proceedings of the National Academy of Sciences (PNAS) have announced the public beta of the first journal to be launched on HighWire's new platform, H2O. The new site, at, represents a major re-design of PNAS Online.

A feature of the new interface keeps readers in context as they conduct their research, minimising 'pogo-sticking' in and out of pages, to find all the information and services they need without opening a new window. The platform infrastructure is highly permeable, flexible and modular so that it can easily be built upon using standards-based Internet technologies, now and into the future. Features that keep users in context include Abstract Preview; Figure expansion in place; Tag-along navigation; Popular-articles list; and Easier scanning and reading.

PNAS and HighWire worked together to create the new PNAS Online interface. The new look and layout are the result of many months of research, analysis and testing on usability, including professional design review by iFactory and a usability-heuristics evaluation from Nielsen/Norman Group. All personalisation settings, bookmarks or stored URLs that users have established will remain in place and be updated whether they make changes in the beta site or on the standard PNAS site (

PNAS grants free access to content after six months. For those accessing the site without a subscription, full text articles published prior to September 2007 are available for free.
