## Description

This encyclopedia contains more than 5000 integer sequences, over half of which have never before been catalogued. Because the sequences are presented in the most natural form, and arranged for easy reference, this book is easier to use than the authors earlier classic *A Handbook of Integer Sequences<$>. The Encyclopedia<$> gives the name, mathematical description, and citations to literature for each sequence. Following sequences of particular interest, thereare essays on their origins, uses, and connections to related sequences (all cross-referenced). A valuable new feature to this text is the inclusion of a number of interesting diagrams and illustrations related to selected sequences.*

The initial chapters are both amusing and enlightening. They serve as a delightful introduction to the subject and a short course on how to identify and work with integer sequences. This encyclopedia brings Sloanes ground-breaking *Handbook<$> up to date, more than doubling its size, and linking both the old and the new material to an extensive bibliography (over 25 pages long), of current and classic references. An index to all the sequences in the book is also available separately on disk in Macintosh and IBM formats.*

## Reviews

@qu:In spite of the large number of published mathematical tables, until the appearance of the first authors *A Handbook of Integer Sequences<$> in 1974 there was no table of sequences of integers. The 1974 book remedied this situation to a certain extent, and the present work is a greatly expanded version of that book. The main table contains 5488 sequences of integers (compared with 2372 in the first book), collected from all branches of mathematics and science. The sequences arearranged in numerical order, and for each one a brief description and a reference is given.
An invaluable tool. I shall say no more about this marvelous reference except that every recreational mathematician should buy a copy forthwith.

@qu:There are twice as many sequences as there were in Sloanes Handbook<$> and those who have the Handbook<$> will want The Encyclopedia<$>....Many people who have searched in vain for some of the sequences missing from the Handbook<$> will be quick to get copies of this new and expanded version to track down these missing sequences.

@qu:What's the next whole number in this sequence: 2, 4, 7, 11, 16, 22, 29? The answer can be found in one of more than 5,000 entries in The Encyclopedia of Integer Sequences.<$>
@source:--SCIENCE NEWS
@qu:The number of sequences cataloged here is more than double the tally of the previous incarnation....If libraries shelve this book in the reference section, they should consider aquiring a second copy for circulation. The book will likely be in high demand, not just by researchers, but by browsers at all levels who will especially appreciate the entertaining commentaries interspersed every few pages throughout the encyclopedia. Highly recommended for all academic libraries.
@source:--CHOICE
@qu:"Incomparable, eccentric, yet very useful. Contains thousands of 'well-defined and interesting' infinite integer sequences together with references for each. Sequences are arranged lexicographically and (to minimize errors) typeset from computer tape. If you ever wondered what comes after 1,2,4,8,18,71...this is the place to look it up."
