Good list but needs updated - 2 of the links that I opened are no longer available.
We have a similar problem at work, people put up spreadsheets with links to standards or specifications.
An "owner" of the spreadsheet then needs to be identified whose task is to check the spreadsheet every 6 months to ensure the correct information is available or to be the point of contact if someone wants to update the spreadsheet.
