What one reviewer said about A Bibliography of the Works of Samuel Johnson, 1731-1759 : Treating His Published Works from the Beginnings to 1984 by J. D. Fleeman:
J. D. Fleeman has left us a hefty 2-volume set of incredible value to some people, but perhaps not to many. It's an extremely comprehensive listing of various editions of Johnson's works, both as sets and isolated volumes. The date range is from original editions when Johnson lived (18th C), up to recent times. Some of what is here is surprising - - such listings of Johnson's Dictionary in foreign languages, which initially caused me surprise (but were understandable with more thought).
I have used it on occasion in placing bids on eBay (it has helped me understand editions such as a 1970's facsimile reprint of the 1st edition of Johnson's Dictionary), as well as when buying 19th C editions of his books over the Internet, and helped take some of the guesswork out of what I was purchasing. It's told me more about some of the editions I already own. It has also helped me anser questions from visitors to my Johnson website.
I imagine that this set is very valuable to the specialist, but I imagine that even the specialists would prefer to borrow it from their local library than to buy it. While this is a monumental achievement, and deserves all five of the stars I've given it, at $460 for the 2 volumes together, I think most people's uses for this would be limited.
