I only have time for a quick response right now.

I searched eric.ed.gov.  I don't believe that result #10 is in Googel Scholar.

"Using Mobile Device for Learning: From Students' Perspective"

If you use the advanced search, you can limit to ED numbers (as
opposed to EJ numbers which are journals).  I believe that a high % of
the EDs will not be in Google Scholar.

Also, I don't believe that GS allows you to sort by citation count.
Several academic databases do.  This can help you quickly identify the
most important articles.

Hi All

When conducting literature reviews, especially systematic literature
reviews, academic researchers usually consult a number of data bases
(Medline, EBSCO, etc.).  Given that Google Scholar indexes so much, is
there any reason to use these other data bases at all, rather than to
simply go to Google Scholar?

I am aware that some of these data bases allow for a more detailed
type of search (e.g. terms found in abstract only, etc), but if I were
doing a search for all articles that have, for example, "mobile
learning" in the their text, would it not make more sense to simply
perform that initial search in Google Scholar, and ignore the other
academic databases?  What reference could they offer me that Google
Scholar doesn't?

(And yes, I'm aware, that Google Scholar will pull up far more grey
literature, but that is part of the manual sifting process that I
would have to perform anyway.).

Does anyone know of a comparison study that has been performed?

Thanks.

Regards

Ken
