Eve Source trumps the evelopedia by the way.
And anything ingame.
that's the official CCP word.
The funny thing is (and I'm still pretty inexperienced with PF, so I may just be a dummy), that Source falls far short of the existing online resources in pretty much every respect save concept art. Furthermore, while a great deal more background and flavor information is available online, I'm not seeing much in the way of direct contravention of Source. It's more like Source is the general overview which encourages you to seek details elsewhere.
Since I'm still fairly ignorant, does anyone have solid examples of how Source has trumped online PF?
Edit: To clarify, I'm not saying I don't believe Source to be the definitive lore guide, just that it is diminutive in comparison to other available PF materials, reading more like an introductory guide (which in itself can be pretty useful).
