The annotated chronicles is the original trilogy bound into one massive tome, with annotations in the side that give further insight into the making of, as well as the world of, Krynn (It even has recipes!). It is entirely possible to read the book and avoid the spoilers, just in my case I would occasionally read snippets by accident. it's also about 20-30$ more (as a ten year old this book was literally my pride and joy
The best I can say (and I may be wrong) is that while LOTR created the fantasy genre as we know it, Dragons of Autumn Twilight, Winter's Night and Spring Dawning, essentially made them mainstream -as much as possible with fantasy- Without these three books, entire fantasy worlds known worldwide i.e. Drizzit Dudden/forgotten realms, would have never happened. I hate to sound pushy, but more so than the wheel of time, Malazan book of the fallen (My favorite series since being introduced to it) a song of Ice and fire, these books should be read.
I may be slightly biased.
