• A Handbook of Integer Sequences, by N. J. A. Sloane (1973). This might be considered the `first edition' of the book under review. It contained only 2372 sequences, compared to 5488 in the current volume. As of this writing, there are 6222 basic entries in the dynamic online version, and because of the transformations many more sequences can be identified.
• A Dictionary of Real Numbers, by Borwein & Borwein (1990).
• ISC--the Inverse Symbolic Calculator, which can be found easily from

  When you give this program an approximation to a real number, it will do its best to decide what that number `really' is--in essence, this is a greatly expanded online version of the Dictionary of Real Numbers, mentioned above. For example, the ISC describes as the `lemniscate number'. Simon Plouffe is currently working on this program here at the Centre.

• gfun the Generating Function Package by Salvy et al [4]. This Maple package from the share library contains functions for manipulating sequences, linear recurrences, differential equations, and generating functions of various types. Simon Plouffe and F. Bergeron had some input into this package, as well.
• numapprox[pade] (formerly convert/ratpoly) in Maple. This utility uses clever algorithms to convert power series into Padé approximants.
• Mathematica has facilities for conversion of series into Padé approximants and the like as well.
