TITLE: MathSciNet vs Google Scholar
QUESTION [25 upvotes]: What are the pros and cons of the MathSciNet database vs Google Scholar?
I don't have access to Mathscinet so this question is out of curiosity, and also this question where MathSciNet is used to find paper counts. I reckon Google Scholar will almost always be the more comprehensive of the two with higher paper counts for any particular author and includes papers that don't use the MSC codes as well papers from other subjects that may be of mathematical interest but aren't included in mathscinet.
One definitely annoying thing about Google is that in the advanced search it doesn't have a mathematics only category, but lumps it in with computer science and engineering so you sometimes need to add something like -"computer science" -"engineering" mathematics to your search term to filter out unwanted results, which isn't ideal.

REPLY [5 votes]: One disadvantage of Google Scholar is that it is not quite reliable in recognizing the same paper coming from different sources (arXiv, multiple preprint servers, journal website, the author's homepage, etc). This leads to a citation overcounting and unreliable metrics.
On the other hand, the author can update his own profile and merge all these duplicates. In this case, Google Scholar is quite accurate and powerful. Since not a lot of authors do this, unless Google implements some automatic merging algorithm, the metrics it provides are not very reliable (for what they matter, anyway).
