Walk into the library with no plan. The shelf next to the one you came for is where it gets interesting.

Searching for something specific gets you that thing and nothing else, which is efficient and also a closed loop. Physical shelves put unrelated neighbors in front of you, arranged by a system that had no idea what you wanted. That accident is the useful part. Nothing can surprise you when the only thing shown is what you already asked for.

Go with a vague direction rather than a title this week and wander a section. Pull down three things you have no reason to pull down. Read the first page of each standing up, and take home whichever one you did not expect to want.
