Poorly formatted. Like the premise, but don't count on the table of contents to help very well.

Love me some Keller, and would love to rank this higher, BUT Logos' implmentation here is sub-par for two reasons: 1) there is NO audio, and 2) the "fully integrated Logos Edition" is, uh, poor.

This is porn.

This edition is from 1990; it was updated in 2013. I'd happily pay $20 for on in my Logos library if it was the 2013 edition (a premium over the $14 print version), but for one that's 23 years out of date? So far I've looked for two books to add to my library, and Logos is two-for-two in having a VERY old edition. I'd suggest looking carefully.
