Ways to cope with exponential growth of knowledge

books which leave out what's not essential are more important than books which tell you everything because you don't want to know everything.

Hamming said it 28 years ago.
Now Wikipedia plays role of "essential-only" books.

Does it mean that Russian math school does not like defining calculus as a separate subfield in math?
