Looking for 3rd Party Documentation on Cognos Planning

[abernabr]

Hello,
I am new to the group and Cognos, but will try to keep the stupid questions to myself. However, I am having a hard time finding any reference materials that were published by anyone other than Cognos/IBM.

Does anyone have any suggestions on a "good" reference book that are worth purchasing?

BTW: I already have access to manuals and training books, but would like to supplement my materials.

Any thoughts or suggestions are greatly appreciated.

Thanks
