A Picard Easter egg

While watching the first episode of the new Star Trek series just now I noticed a nice little Easter egg:

Admiral Picard (retired) apparently has the same 1982 science fiction book club edition of The Complete Robot handy on his desk as I have on mine:

though frankly, his copy seems to be in better shape than mine.

Anyone know what the book below it is?

UPDATE: My friend Brian R has identified a likely candidate for the second book. It appears to be the Easton Press edition of The Three Musketeers:

UPDATE: Later episodes of the series confirm these hypotheses; apparently these were not so much Easter eggs as subtle foreshadowing.
