I've got several SALs named thing like "books", "movies and dvd", "eating out", "photography". All the individual books and movies just have the on-hold context of "list" so they're inactive.

If I decide I want to actually buy (or in your case read) a book just assign it an active context (but can just keep it in the same list) - then it shows up where i'll see it. Usually "errands - weekday" context for me, or maybe "home" for you if you've got the book already...
