This shows the amount of math literature to be digitized in order
to create a "DML".
Some estimates are higher, on the other hand:
MathSciNet has links to more than 700,000 "original articles"
-- these are probably "born digital" articles.
According to MathSciNet's
"Facts
and Figures" it gained ca. 800,000 entries since 1995,
which may have been an "overall electronic" publishing border.
