Without seeking to offend any of the editors involved in the decision to remove references to spiritoftheages.com, the comments - including that site has "[n]o encyclopedic purpose for ...[Wikipedia] readers" - seems inaccurate and the action to remove links based upon such comments removes links for readers interested in that artists and artwork accessible on the various links. In making that comment, I would note that spiritoftheages.com is clearly under continuous development - I have noted regular revisions to the site with many of the more recent updates involving the inclusion of considerable material derived from original sources (inclusive of details around publishing, illustrations, the artists and the text related to the illustrations). Some of that information has directly contributed to Wikipedia articles. Further, in a number of cases, the link site (spiritoftheages.com) has highly detailed information of research value that does not otherwise appear to be available on the web - examples that spring to mind are the emerging practice on the site to accompany images with associated text (as is the case in Vernon Hill's illustrations to Ballads Weird and Wonderful), Holbein's illustrations to The Praise of Folly (Moriae Encomium) [in that example, the illustrations are shown with both French and English translations of Erasmus' text], illustrations shown from Der Weiss Kunig (where extracts of translated text from the medieval German is shown on occasions), Der Todten-Tantz (where German and English text is shown with the associated image) and Michaud's The History of the Crusades (where Dore's illustrations are shown with Michaud's associated text). I do appreciate the comments about spam and the like, but believe this to be a significant resource that has relevance to Wikipedia users (and rather than go ahead with inserting references again, would appreciate some considered comment about the points I have raised before taking such potentially inflammatory action).
