I am nominating this featured article for review because there are concerns listed on the talk page about the overreliance and reliability of the Oman source. Concerns with the source were raised in the article's FAC, and the overreliance concern was raised in 2007 and 2008 on the article's talk page, and mentioned again in March 2022. I am opening this review to see if editors more familiar in this subject area can evaluate Oman's inclusion and/or find new sources to include in the article. I did a quick search databases and found potential new sources; I'm happy to list them below if anyone is interested in evaluating them and improving the article.
