•    Beginning with a level of free access, and then through various subscription levels, not only can you find financial and general management info on specific organizations, but links, training and resources for a huge number of nonprofit management issues.  
•    A wonderful source for nonprofit articles of all sorts, accessed from a monthly e-newsletter.
•    I use this database more than any other to find information on nonprofits of all kinds.
