Web of Science (WoS) is the de facto data source for publication analysis. A
typical search in WoS would be "English articles, SCI-EXPANDED, All years".

There is a problem with reproducibility of results from before 2008. In
other words, a search done today will give different results than the same
search done in 2007. Of course there are always slight differences
(especially for recent years) as publications are retroactively added, but
in this case I am talking about a non-trivial difference caused by a change
in the structure of the database.

See for more information.
