"Why We Nap" - Stampi - next to impossible to find. It coined the word polyphasic (and monophasic) sleep.
It's exploratory, but pretty good science. It's basically a study of solo sail-boat racers- long distance. They have to get little naps in, but they have to stay awake enough to take advantage of wind and water currents for days and days.
Other than that, at least last time I checked a year or two ago, all sleep scientists had written it off as "sleep deprivation" which they feel they already have a good handle on (it's evil), and therefore they are very disinterested in actually studying it.
