The Book Versions

Neil Sloane started collecting number sequences when he was
a graduate student
at Cornell University in the mid1960's,
in an attempt to identify a sequence that had arisen
in the work on his dissertation.

For the full story, see his article
"My Favorite Integer Sequences", in
Sequences and their Applications (Proceedings of SETA '98),
C. Ding, T. Helleseth and H. Niederreiter (editors),
SpringerVerlag, London, 1999, pp. 103130. Available in
pdf or
postscript
format.

The idea of a "dictionary" of integer sequences was received with enthusiasm by many
people, and in 1973 Academic Press published
A Handbook of Integer Sequences,
containing about 2400 sequences.

Over the next twenty years an enormous amount of new material arrived,
preprints, reprints, postcards, typewritten letters, handwritten letters, etc.,
and it was not until 1995 that  with Simon Plouffe's help 
the sequel appeared:
The Encyclopedia of Integer Sequences,
N. J. A. Sloane and S. Plouffe,
Academic Press,
San Diego, 1995, 587 pp.
ISBN 0125586302.
This contained about 5500 sequences.

The book is still useful
since it contains many of the most important sequences.
The database (which is now maybe a thousand times the size of the book)
is too huge to use except as a reference.
