Some annotation is probably appropriate:
It's all Traveller save for the EC Tubb Dumarest books top right (and, arguably, the three GURPS general books (one 3rd edition and two 4th edition) next to GURPS Traveller[1])
LEFT
1st shelf down - classic Traveller digest sized, JTAS, other magazines/fanzines from the 80s, Signal GK (digest sized), BITS little white books, various novels
2nd shelf down - classic Traveller US letter sized, MegaTraveller, TNE, TNE 1248, Marc Miller's Traveller
3rd shelf down - between the boxed games is 2300AD and Finnish 2300AD
[my very first acquisition was the Deluxe Traveller - the second item from the left end of the shelf]
4th shelf down - miniatures, Traveller dice and t-shirts (forgot to get my two BITs polo shirts out of cupboard for this) (also forgot to round up two laptop bags and a rucksack and a glass tankard as they live elsewhere - all TravCon freebies from different years)
5th shelf down - GURPS Traveller, T20, coloured document wallets are my 'big' adventures not yet published and my earlier bibliographies (in white) and other bits I've written.
