Xuanzang Temple, Nanjing (Wikipedia)

Xuanzang Temple, Nanjing, the Wikipedia article on the site, is a community edited encyclopedic account of the parietal skull bone relic attributed to the seventh century pilgrim-monk Xuanzang, unearthed in 1942 during Japanese wartime construction work in Nanjing, and its subsequent division among temples in China, Japan, Taiwan and India. Its strength is that a well developed Wikipedia article on a documented relic with a twentieth century discovery date typically draws together press and institutional sources on that discovery and division across multiple countries into one accessible account, useful for that kind of stable factual chronology. Its limit is that Wikipedia is a continuously and anonymously editable reference rather than a peer reviewed source, so it is fit for the documented discovery and distribution history but a claim resting on the relic's authentication as genuinely Xuanzang's own remains needs the archaeological or Buddhist institutional scholarship the article itself would need to cite directly.
