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.
