For those interested in learning about the various sects of Mormonism, there is an excellent book called, "Scattering of the Saints: Schisms within Mormonism".
The following graphic is of the front cover and shows the presidents of a few of the various offshoot churches. The image is a little hard to read, but the book itself goes through all the various churches.
Once the image comes up, you can click on it to make it a little bigger.
Here is a link to the book on Amazon.
And here and here and here is some online information on a few of the sects (a number of which have their own websites).
