Tropic of Cancer

I don't particularly have an opinion on this library book kerfuffle overall (briefly, for those too lazy to click a link: the library book rules allow users to take out as many books as they want for as long as the user wants to, is there something wrong with taking out 100+ books for six months or so?), but I think at least one part of the argument proceeds too quickly. At a couple of points, when discussing the recall system, Will assumes fully informed preferences on the part of other library users. What if they don't understand just by reading the title and whatever other information is available in the card catalog how much they'd enjoy the book or how useful it would be for their project, but would discover this if the book were physically present on the shelf? Granting partially informed preferences block a couple of steps in the argument, though I don't think they rebut its conclusion.
