Browsing is the opposite of "search." Search is precise, browsing is
imprecise. When you search, you find what you were looking for; when you
browse, you find what you were not looking for. Search corrects your
knowledge, browsing corrects your ignorance. Search narrows, browsing
enlarges. It does so by means of accidents, of unexpected adjacencies and
improbable associations. On Amazon, by contrast, there are no accidents.
Its adjacencies are expected and its associations are probable, because it
is programmed for precedents. It takes you to where you have already
been--to what you have already bought or thought of buying, and to similar
things. It sells similarities. After all, serendipity is a poor business
model. But serendipity is how the spirit is renewed; and a record store,
like a bookstore, is nothing less than an institution of spiritual renewal.
