A huge store of material for HR and training people, with links to some of the best on-line discussion groups too.

Some notes for visitors (from the "First-timers" page):

Library Not to Be Used to Generate Profits
1. The library includes materials that were provided for free by others in the community. Therefore, it would be very inappropriate to use the library in any form that generates profits.
2. The library can be included in nonprofit-related programs that generate funds only to the extent needed to provide the library's services.
3. Feel free to link to the library! We welcome and appreciate it!

Focus of the Library
The focus of the library is on free, on-line management resources. The term "management" includes the activities necessary to plan, organize, lead and coordinate activities in an organization, whether for-profit or nonprofit.
