This shows the amount of math literature to be collected in order to create a "DML".
Some estimates are higher, on the other hand:
MathSciNet has links to more than 1.500.000 "original articles"
-- these are probably "born digital" articles.
MathSciNet gained ca. 1,490,000 entries since 1995 ( = "overall electronic publishing border", compare:
