This is my favorite reference for enterprise patterns:

An analysis pattern is a collaboration that appears in many domain models. Here's an example:

Here is the original pattern catalog for software engineers:

[Go4]               Erich Gamma, Richard helm, Ralph Johnson, and John Vlissides. Design Patterns, Elements of Reusable Object-Oriented Software. Addison Wesley, Reading, MA. 1995.

This is my favorite catalog:

[POSA]           Frank Buschmann, Regine Meunier, Hans Rohnert, Peter Sommerlad, and Michael Stal. Pattern Oriented Software Architecture: A System of Patterns. Wiley. New York, NY. 1998.

It's also easy to find patterns on the web.
