The Journal of Integer Sequences is a peer-reviewed open-access academic journal in mathematics, specializing in research papers about integer sequences.

[1] Sloane had previously published two books on integer sequences, and in 1996 he founded the On-Line Encyclopedia of Integer Sequences (OEIS).

Needing an outlet for research papers concerning the sequences he was collecting in the OEIS, he founded the journal.

[2][3] Since 2002 the journal has been hosted by the David R. Cheriton School of Computer Science at the University of Waterloo, with Waterloo professor Jeffrey Shallit as its editor-in-chief.

There are no page charges for authors, and all papers are free to all readers.
