Google Scholar
In November 2004, Google introduced a new tool called Google Scholar. Here's how
the Google site describes it "Google Scholar enables you to search specifically for
scholarly literature, including peer-reviewed papers, theses, books, preprints,
abstracts and technical reports from all broad areas of research. Use Google
Scholar to find articles from a wide variety of academic publishers, professional
societies, preprint repositories and universities, as well as scholarly articles available
across the web." Moreover, "Google Scholar. ..automatically analyzes and extracts
citations and presents them as separate results, even if the documents they refer to
are not online. This means your search results may include citations of older works
and seminal articles that appear only in books or other offline publications." Google
Scholar not only indexes journal articles, dissertations, and technical reports, it also
indexes books, which means you can use Google's new Library Search (OCLC's
WorldCat search) to locate the book in a local library or find a place to purchase the
book online.
Although a number of scholarly search sites and tools already exist-e.g., CiteSeer,
DOAJ, ArXiv, and even Google's own partnership with IEEE-the fact that the
premier search engine has branched off into scholarly search is obviously
significant. Google Scholar searches across a far wider range of sources than any
other publicly available scholarly search tool currently available. Users should be
able to read at least an abstract of articles that require registration and access the
full text if they or their institution have a subscription for the content. The best thing
about Google Scholar is that it gives users the range, power, and flexibility of
Google. As far as I can tell, all the types of Google syntax-site:, inur/:, filetype:,
etc.-work with Google Scholar. You can limit your search to file type using either
the fi/etype: or ext: syntax, e.g., [extpdf] (fi/etype: and ext: work interchangeably).
The most useful addition to Google Scholar is probably the new author: syntax
(which, by the way, already existed in Google Groups search).
As you can see from this query, Google Scholar searches and retrieves scholarly
references from many types of sources and also provides a handy "Cited by" link
that shows all the pages referring to the original work.
