: I'm responding to some of this here rather than at my own talk page. And here's a ping for .  

 :We could use any of those references where people write about his work and publications. Please give the following information for each one: author name or names, journal title (in the original language), volume number, issue number if you have it, date (at least year), article title, and pages the article is on. The URL of an online version - or an online abstract, which is all there is for some journals - is helpful but not necessary, so yes, please give the Google URL if you have it (and in case you are working with a college library, if you have a jstor or doi number, include it please.) You can list these here on the article talk page or put them in the article as references. To do the latter, type the information between a  tag and a  tag at the end of the sentence or sentence section that the reference supports. The article is using citation templates; don't worry, someone else can convert the raw data into that format (and possibly find an online version if you could not). If that's too complicated, just list that information here for each one. 

 :Don't ask people for letters; since we are an encyclopedia, private communications are a type of reference we avoid. But yes, newspaper articles would be useful. The same kind of full information, please, including the accurate title in the original language. Since newspaper articles are unlikely to be online, it would be very helpful if you would type out relevant short quotations from these. Adding a translation is helpful, but the original wording enables multilingual Wikipedians to search further and to tweak the translation for accuracy -) In the same vein, yes please, could you add the original wording for the quotations you previously translated that are in the article? Here would be fine.  

 :I'm not sure about the letter from the queen. Perhaps Bazj or someone else has a thought. 

 :Yes, the list of his published papers was removed and replaced by a link to an online list. However, one of the weak points of the article at present is that the introduction lists scientific contributions he made, and the article doesn't at present substantiate those. I'm hoping the citations you mention will enable us to fill that gap, and that may lead us to list a few of his papers that those sources say were particularly significant in the field. That is the preferred way to deal with a prolifically published academic here: to list only selected works that have been mentioned in reliable sources as particularly important, but to link to a complete bibliography. 

 :I think that covers most of it. I've responded about images on my talk page. Have I left anything out?
