The Uighur Empire according to the Tʻang dynastic histories: A study in Sino-Uighur relations, 744-840 (Asian publications series)

Very good introduction to the Uighurs of the Tang Dynasty period followed by extracts from the Chinese texts (unfortunately, there are few if any extant Uighur texts from this period with which to balance the Chinese). A bit slow reading at times due to the lack of familiarity most readers will have with Uighur historical names, and since the Chinese names also are transcribed in Wade-Giles, at times frustrating for those who even know their Tang history.
