I don't know if you talked about Terry's canon and non-canon opinion in your introduction, but I really think you should, if only because it provides an explanation for some glaring inconsistencies between Terry's "approved list" and those that were definitely written without his supervision (and vision for Shadow World) - The Shade of the Sinking Plain being a prime example if the latter, but Sky Giants, among others, can be included in that list. I mean, Sky Giants can be used as inspiration material, but it only pays lip service to the Shadow World canon, and Terry barely mentions its existence in his products (during the timeline, in the dates about the expansion of Rhakhaan into Wuliris).
I also think that you should refrain from including Duranaki Chronicles since, as far as I know, it was published without Terry's approval (and could be argued to constitute a copyright breach). Which is sad in a way, because the parts that take place on Kulthea are more or less faithful to canon [I would advise people who are interested in using it as inspiration to stick to the first volume and ignore the second - the author was obviously interested in Shadow World but not in Space Master's Imperium, and the second is more than half space opera :p]
I find it odd that you don't include a single book from Terry's fourth edition work - SWMA4, Powers of Light and Darkness, Emer1-3, Xa-ar, and the revised Haalkitaine, Eidolon and Jaiman books - except Tales of the Green Gryphon. I would have started with the books that provide the most context. I mean, Vog Mur is great (and certainly a fond memory), but it does not provide much of a framework for Shadow World, since it was written before the World of Loremasters became Shadow World (Tanara and Iron Wind were in the same situation - all three are among the best SW products in my opinion, but the adaptation work required is not insignificant if you want to use those setting in the 'current time' of the official timeline).
