I just saw this over on the Wizards FR board, and thought it might be of interest (I'm not sure if it's old news or not, but oh well
).

Savages Species is a core D&D product that examines all the issues of playing monsters as characters, and provides specific information on playing something like 50+ monsters as characters. One of the questions it addresses is how to play even high-HD monsters such as mind flayers or aboleths as 1st-level characters, by introducing the notion of a "monster class" (in other words, your 1st-level mind flayer is a 1-HD character with very few of its eventual special abilities).
Races of Faerun examines the most prevalent races of the Forgotten Realms setting, describing their culture, society, outlook, and providing plenty of new "crunchy bits" by way of race-specific feats, spells, items, and so on. It emphasizes how the races fit into Faerun. Some of the more common "minor monstrous races" that might be played as characters (aarakocras, centaurs, kir-lanans, lycanthropes, and a couple of others) get some attention too, but unlike Savage Species, these guys get ECLs and that's it -- Races of Faerun doesn't tell you how to play a centaur as a 1st-level, 1-HD character. By way of comparison, Races of Faerun has a 30-page chapter on humans that gives about 4-5 pages each on the 7 major human ethnic groups, their history, their culture, their magic and lore, and other such details. Overall, Races of Faerun touches on a couple of related topics as Savage Species, but there's little overlap.
The races given in Unapproachable East include some races that are very specific to the eastern parts of Faerun, and aren't as widely spread as the races and subraces in Races of Faerun. For example, due to the Kara-Turan influence in Thesk, spirit folk (derived from the Oriental Adventures spirit folk, but not quite the same) are a PC race in the East. Other potential PC races given in the Unapproachable East include gnolls (quite common in Thay), taers, hagspawns (the sons of hags), and two new races we haven't told you about yet. The gnoll overlaps with Savage Species a little bit, but the rest of the U-East races don't overlap with either Savage Species or Races of Faerun.
Hope that helps.
