[LIS-Forum] Google SCholar

[Sathya]

To the extent I understand, Google and Google scholar are completely two
different services.

Google is simply a search engine. It scrawls almost the entire web at
different frequencies (some sites once an hour and many sites may be once a
month or quarter a year), caches the scrawled web and does
machine indexing.  It does not store and compile the content. It is simply
a temporary index to cached content.

Google Scholar is a database. It is a citation database like Scopus or Web
of Science. The content is harvested, stored, compiled and indexed.  Unlike
other databases which may have manually controlled editorial process,
Google does not seem do anything with the data that needs
manual intervention.  This could be one of the  reasons why data quality in
Google scholar is not dependable.   Coverage of OA content in Google
Scholar is very limited. But, we all trust Google a lot because  Google has
acquired the reputation of  "the God" of the information world ....... the
mysterious unknown.


Google's search engine is of course very powerful and highly advanced.
