Deletion of Society for Industrial and Applied Mathematics

Comment: This is the major international society for its discipline, with over 500 article-space links. As well as the Fellow category pointed to by DGG, I would also point to :Category:SIAM academic journals as evidence of the significance of this society as the publisher of several major and well-respected academic journals. It has nontrivial coverage in independent sources including http://www-history.mcs.st-andrews.ac.uk/Societies/SIAM.html https://books.google.com.au/books?id=yPQaAQAAMAAJ https://books.google.com.au/books?id=Uo4_AQAAIAAJ https://books.google.com.au/books?id=dxMpAQAAMAAJ. An important subject for the encyclopedia to cover, and one that passes . This is the kind of AfD that makes Wikipedia look ridiculous to the outside world:&nbsp;it's obviously a significant subject, so why are we even considering deleting it? Significance is not notability and that's especially true in general for academic societies but this one passes notability as well

Comment: I've considering withdrawing, but this is not a "ridiculous" nomination, and stating such is sophomoric. Herein, some, but not all of the arguments for the article to be retained are rather subjective relative to |notability guidelines. Since this is an ''important'' organization, one would think that many reliable sources providing significant coverage would be easily and readily available relative to this importance, particularly since the organization exists to this very day. Where is the significant coverage? I checked out the sources provided above by David Eppstein, which is appreciated: The first one is all right being sourced from academia and providing a brief summary, but, the https://books.google.com.au/books?id=yPQaAQAAMAAJ&focus=searchwithinvolume&q=Society+for+Industrial+and+Applied+Mathematics second appears to only have passing mentions and is limited to one page (430), the https://books.google.com.au/books?id=Uo4_AQAAIAAJ&focus=searchwithinvolume&q=Society+for+Industrial+and+Applied+Mathematics third is a bit amgiguous with snippet views, and the https://books.google.com.au/books?id=dxMpAQAAMAAJ&focus=searchwithinvolume&q=Society+for+Industrial+and+Applied+Mathematics fourth appears to only be a passing mention on page 10. Now, I understand that notability guidelines are just that, guidelines, and exceptions exist, but again, if this is so notable, where is the significant coverage
