Those folk at Google are certainly stirring things up with the launch of 'Google Scholar (Beta)' a variant of the search engine to access the scholarly literature.

According to the New York Times (you'll need to register):

The engineer who led the project, Anurag Acharya, said the company had received broad cooperation from academic, scientific and technical publishers like the Association of Computing Machinery, Nature, the Institute of Electrical and Electronics Engineers and the Online Computer Library Center.

The new Google service, which includes a listing of scientific citations as well as ways to find materials at libraries that are not online, will not initially include the text advertisements that are shown on standard pages for Google search results.

Testing something like this is rather tricky when the coverage is unknown. However, I tried just a simple, but slightly obscure search phrase, "colliery spoil" and got a list of 146 items. Some are listed as 'CITATION', for exampe:

[CITATION] Effective passive treatment of aluminium-rich, acidic colliery spoil drainage using a compost … - Web Search
PL Younger, TP Curtis, A Jarvis, R Pennell - Cited by 10
Journal of the Chartered Institution of Water and …, 1997

Click on the 'Web search' link and, as you see, it does just that; click on the 'Cited by 10' link and you are given a list of the ten sources that have cited this item, with the same layout and more links to items that cite the cited items—one could get rather dizzy going through this lot!

Other items in the original list are links to information on the Web, although not always the complete document. For example, this link leads to an abstract in PubMed, not to the original document:

Substrate characterisation for a subsurface reactive barrier to treat colliery spoil leachate
PW Amos, PL Younger - Cited by 4
Substrate characterisation for a subsurface reactive barrier to treat colliery spoil leachate. Amos PW, Younger PL. FaberMaunsell ...
Water Research, 2003 - ncbi.nlm.nih.gov

The 146 items consisted of 35 Citation entries and 111 Web links
