Books vs blogs vs MCP

Which should i be reading or listening to because there's MCP that is 7 hours long and has 'Finding Vanessa' and calls Tony as Carlos.

My though train on the whole thing is the books are the base line of everything in the sense that it shows and tells us everything that happens in the gas station and the blog which im guessing is what MCP narrated is the blog he talks about posting in the books?

Please someone explain
