The Complete Ferengi Rules of Acquisition (projectsanctuary.com)

I recognize a lot of them from DS9, but I'm not sure if they all came from the show. I really enjoyed how the Ferengi were portrayed in DS9 making pilgrimages to WallStreet...kinda funny.

I think the series never mentioned all of the rules. Memory Alpha (already linked above) is strict in adhering to canon and has a list of rules that appeared in the series: http://memory-alpha.wikia.com/wiki/Rules_of_Acquisition

Guess the rest is made up or from non-canon publications.

The full list was never mentioned in the show, but I believe one of the writers (Ira Behr?) subsequently published a full list as a separate book. So probably not official canon but about as close as it gets.

Doesn't memory beta have like a zillion ads and popups?

Memory-Alpha[0] lists that rule as "Knowledge equals profit" so probably a mistake.
