The first task is easy.

right. and thus your first d.v.d. -- the one with all the e-texts that have few pictures, or none at all -- is set.

The second, not so much because the catalog doesn't yet contain categorical data for each title.

at this point in time, i would guess that any e-text that doesn't go on the first d.v.d. (because it has more than a few pictures in it) would go on the second d.v.d. so it's set too... a third d.v.d. might contain just the audio files. (and nobody wants the human genome files.) -bowerbird
