More than a mere 'supply catalogue', this book not only presents a vast array of items that Traveller characters might wish to have in their possession, it links them to Tech Level and provides the information a referee might need to decide whether or not each item is actually available. To this end, it begins with a lengthy discussion of what lies behind the bare numbers of a Tech Level, and looking to the dizzy heights of TL20 or beyond.
This initial discussion continues with a look at what Tech Level means within a society and how imports may exceed local Tech Level, often by quite a lot, although you'll probably need to import support personnel to keep high level items running as well. Also it may not be uniform: some areas such as transportation or communications may be higher (or lower) than the average TL of a world that appears in the records. The nature of society changes as TL increases as well, with more leisure time and the need for more sophisticated forms of entertainment as well as greater trade opportunities as it rises, with more people being engaged in activities other than day-to-day survival. There are also notes on low-tech versions of items, representing invention, prototyping and the creation of low-tech solutions to higher-tech problems. Likewise, a higher-tech version of a lower-tech item can be devised. All quite interesting and well worth a read if you want a realistic and varied approach to technology across your galaxy.
This all depends on being able to craft and to understand devices, and rules are provided to enable such cross-TL endeavours. Even once you have determined what is possible, the next question is how legal it might be... and that depends on what the item is, where you want to have it, who you might happen to be, and on a web of permits and restrictions that balance out the needs of local worlds and galactic society - the Imperium, if it exists in your universe - as a whole. Even if you have the correct paperwork, and the necessary funds, it may not be easy to actually find that particular item you're after... All this discussion is underpinned by the necessary game mechanics to enable you to administer the processes involved within your game. This section rounds out with some miscellaneous rules for computer hacking, sensor use, firing artillery and a selection of non-lethal weapon and drug use.
We then move on to the actual items in the catalogue, grouped as Personal and Light Support Weapons, Support and Artillery Weapons, Personal Protection, Survival and Field Equipement, Electronic and Medical Equipment and finally Subsistance and Living Expenses. This makes it easy to find what you're after, or allows you to browse to your heart's content in an area that interests you.
Each section starts with some general discussion of what's there before diving into actual items, which are ordered by TL (lowest to highest) and come with description, statistics and quite often an illustration... although at times you are left guessing as to which drawing in a picture refers to which item in the accompanying text! What's nice is the detail in things like ammunition type and accessories to go with your shiny new purchase. There are also some neat advertisements for specific products, although in general everything is kept pretty generic - a 'shotgun' rather than manufacturer and model details. Needless to say, personal weapons get far more coverage than any other items but there are some neat things tucked away within the survival and medical gear sections.
The discussions on how to handle Tech Level and associated material elevate this work above a mere equipment catalogue, but if it's a shopping spree you're after there is plenty to be had here.
