I just saw an announcement on an email listserv that I’m on for a site which has translations of texts that deal with early Vietnamese history.
The site has English-language translations and searchable Hán text for the following materials:
1. The Outer Annals (Ngoại kỷ) of the Complete Book of the Historical Records of Đại Việt (Đại Việt sử ký toàn thư)
2. The Prefatory Compilation (Tiền biên) of the Imperially Commissioned Itemized Summaries of the Comprehensive Mirror of Việt History (Khâm định Việt sử thông giám cương mục)
3. The Arrayed Tales of Selected Oddities from South of the Passes (Lính Nam chích quái liệt truyện)
The link to the page is here. Enjoy!!
