The On-Line Encyclopedia of Integer Sequences today
You can encounter integer sequences all around combinatorics, number theory, and recreational mathematics. And if there is a multitude of objects of the similar form, then one can create an index for these objects. The On-Line Encyclopedia of Integer Sequences, OEIS, is such an index.
This article covers the On-Line Encyclopedia inclusion criteria, its editorial process, its role in mathematics, and its future.
