"US DoE expands global science gateway – 18 Jun 2008
The US Department of Energy’s (DOE) Office of Scientific and Technical Information has announced that international science portal WorldWideScience.org has expanded its scope to include connections to databases and scientific web sites from over 44 nations.
WorldWideScience.org allows users to question over 200 million science and technology documents not indexed by popular search engines. The portal linked to 12 databases from 10 countries when it debuted in June 2007. The lately expanded service includes 32 national scientific databases and links to portals from 44 countries.
DOE and the British Library along with eight other participating countries first struck an agreement to establish the portal in January 2007. WorldWideScience.org gives science information consumers a single entry point for searching far-reaching science portals in parallel, with only one query, saving time and effort."
Caveat:
IF YOU WANT A CERTAIN ARTICLE, FIRST CHECK THE PRINCETON ONLINE CATALOG FOR THE AVAILABILITY HERE. (Then you may (1)download or print, (2) request via document delivery ,or (3)order directly on your own.)
As great as this service is, I must point out that you will be invited to purchase papers to which the Princeton University Library has already purchased subscriptions. You will want to re -search for the full text article by article, probably most reliably via the online catalog. (Alternatives would be the e-journals listing or the e-journal finder.) Additionally, I must say that not all articles/papers are missed by the popular search engines.
