Card collecting reference books? Which do you own and recommend?

If we're talking price guides and checklists, I have a bunch from the 1970s, 80s, and early 90s, including the first three editions of the Sports Collector's Bible (1975, 1977, 1979); Sport Americana Baseball Card Checklists from 1974, 1975, 1976, and 1978 (each with a rudimentary price guide at the end); the Sport Americana Baseball Card Price Guide (Beckett-Eckes) for each year from 1979-1991, including both covers from 1979 and the hardcover 1980; the Sterling Sports Card Catalog (1977, two copies, one with a price guide inserted); the American Premium Guide to Baseball Cards (1982) by Ron Erbe and Keith Mitchell, which I've posted about here; and the first four editions of the Standard Catalogue of Baseball Cards (1988-90-92-94). That's in addition to many hobby periodicals from the 1950s to the 90s (including a complete run of the first 18 years of Sports Collectors Digest from 1973-91), quite a few non-price-guide books about baseball cards, and quite a few books about trade cards, tobacco cards, and other collectibles.
