Knowledge and information are not the same and it's much easier to manage information than knowledge. For one thing, information is the same for everyone whereas knowledge can differ markedly depending on whose brain it's being processed through.

Amy Gahran at Contentious takes a stab at explaining knowledge vs information:

What's the difference between knowledge and information?

• Information generally includes facts, observations, sensations, and messages. Information is content which informs our minds. It's fuel.

• Knowledge, in contrast, is the human experience of information – it's what our minds DO with all that content. It's the fire in the forge.
