Although only the much-expanded Third Edition and its code in C++ are now supported products, there are many legacy applications that use obsolete Second Edition, or even First Edition, code. Also, computer languages such as C, Fortran, Pascal, Modula 2, BASIC, and Lisp were available only in previous editions. We are pleased that most previous versions are still available for users with a special need for them.

These Numerical Recipes books are still in print or otherwise available and may be ordered from Amazon.com by clicking the respective images.
