Two dead links, probably as a result of websites being reorganised. I found and updated the links. Sources support statements, appear to be RS, no evidence of OR.
It is broad in its coverage.

Comprehensive and focussed, without digressions into unnecessary trivia.
An interesting, comprehensive, well written and researched article that is clearly at GA status, so I have no hesitation in listing it. If you wish to take this further you may need to search out some more free use images as FAC appears to discourage use of non-free. I noticed when checking the article history that the primary contributor was not the nominator. The nominator appears to have made only one recent edit to the article in fact. It is to User:Kohoutek1138 that kudos should go. Congratulations! Jezhotwells (talk) 19:04, 23 July 2011 (UTC)[reply]
