More Googling will help but this is a good set of slides that isn't

James Lattin, J. Douglas Carroll, & Paul E. Green. (2003). Analyzing

Now the first factor accounts for 40% of the variance, and the second has variance of 8% after rotation. Now in layman's terms, what does "% of the variance of each factor" mean?
