Several years ago, I sold most of my Traveller collection, as I had not played the game in a decade, and the books were commanding a high price on eBay. That collection included what I thought was my full collection of LBB's, all eight of the full-size Alien Modules, a lot of MegaTraveller and Traveller: The New Era stuff, and a number of very nice Digest Group Publications materials.
In rummaging through some boxes in the basement this afternoon, I discovered I still have a quite a collection of the Little Black Books, including the original boxed set, with Books 1 through 5 inside (unfortunately missing my two favorites, Scouts and Merchant Prince, which I no doubt sold), Adventures 1 through 4, Double Adventures 1 and 2, Supplements 1 though 7 (except 5), and Journals 2 through 8. I also found my boxed sets of Mayday, Snapshot and Azhanti High Lightning, and about 30 of the 15mm Traveller miniatures.
Traveller has been on my mind lately. Recently, I was looking at James Malizewski's Thousand Suns at my FLGS, but in a moment of nostalgia, purchased the Far Future Enterprise / Quik Link Interactive reprint of the classic 3 LBBs instead, for $12, not realizing I still had the classic Traveller rules at home. I have since read elsewhere that the Mongoose re-imagining of the Traveller rules is very good. I'm curious about the differences between classic Traveller and the Mongoose version, and whether the changes they made improved the game.
