(for posterity: my use of quotemarks left something to be desired here - the quote 'that does..codebook' is Mr. Wong's quote, not my own. I got an uncharacteristically large number of upvotes from the comment above. I suspect had less to do with HNers' appreciation of library science, and more to their expressing appreciation of one's display of their professional bonafides, which I regret, in this case, are not my own to profess.) Although I wonder if HN's commenting system removed any addititional quotemarks I may have placed at the time.
