A spreadsheet left on the web site of the US office of national intelligence includes secret information on the total budget of the US intelligence. Interestingly the not all the required information appears in the document, but combined with other pieces of information made available prior, the total number can be calculated.
This is a very interesting example of the sensitivity of partial data or small pieces of information and not just the big secrets.
