ERPs for Non-Profit Organizations

Reading this week's articles, I could help but think about the limited experience that I've had with Integrated Library Systems. Is an ILS the library world's version of an ERP? It seems to incorporate many similar modules in the "Anatomy of an Enterprise System" depicted by Thomas Davenport (1998, 124). It includes reporting applications, financial applications, inventory and supply applications...as far as I know, our ILS at TCCL doesn't have any human resource management functions, but I can imagine that some might, some day.
