::Thanks for your research on this, LL. I agree that it is perfectly appropriate to mention Mr. Koch's many philanthropic efforts, but an exhaustive listing is neither desirable nor appropriate (Wikipedia is [WP:LIST|not a list). As Abductive points out, his contributions to political organizations or causes don't have similarly comprehensive listings (nor should they be). Perhaps you might condense these into a summary, with appropriate references as you have already documented? Cheers,
