Information on Enumerative Combinatorics


Volume 1 of Enumerative Combinatorics was published by Wadsworth & Brooks/Cole in 1986. A second printing was published by Cambridge University Press in April, 1997. The second printing differs from the first only in (a) the correction of short errors, (b) a list of errata for longer errors, and (c) some Supplementary Problems without solutions.
A paperback edition of Volume 1, second printing, is now available. It differs from the hardcover edition only in a slightly updated list of Errata and Addenda.
Volume 2 was published around January 5, 1999. A paperback edition was published in June, 2001.
Volumes 1 and 2 can be ordered online from Cambridge University Press ( volume 1 and volume 2), Amazon.com, or various other online book sellers.

Note. The material I have gathered on Catalan numbers is being collected into a monograph, to be published by Cambridge University Press in late 2014 or early 2015. This will be the final version of my material on Catalan numbers. The current web page will not be updated until the publication of this monograph. News flash! The manuscript for the monograph Catalan Numbers was sent to CUP on September 4, 2014. Here is the table of contents from the LaTeX file sent to CUP.
