What helps
- For a wrong number: the page, the figure, and the document that states the right one.
- For a new source: the URL of the maker or standards-body page and the sentence that gives the size.
- For a new format: its name, who makes it, and a published size or a documented sample that can support the dimensions.
- For a measurement: identify the product and edition, the instrument, the date, and the repeated raw readings. See how the reference labels physical measurements.
