Related works: Dewey+ vs. Google -Google: -Shows you more of the same (e.g., books from Michael Pollan) -Supports known-item search (searching for a version of a specific work) -Dewey+ (Kindred Works): -Shows you more of the different (cultural-historical accounts of eating and drinking) -Supports exploratory search (exploring a subject/topic space)
