Recording where an idea or fact came from makes publication checks easier. Which document supplied the product information? Who made the quoted statement? Is there permission to use the image?

A source need not be a public link: it might be a current product sheet, a permission record or a project file. Keep internal provenance separate from the references shown to readers. Possessing a document does not mean all of its contents can be shared publicly.

Match each source to a particular claim

I do not treat a source list as a decorative appendix. During writing, I mark which statement depends on which document. A page about the general topic may not support the specific claim in the article. Keep what the source states separate from the interpretation drawn from it.

A specification can verify dimensions without establishing customer satisfaction. A campaign image can document that work existed without demonstrating a sales increase. The writing should not expand the evidence beyond what it supports.

A practical source record

Field Information type
Claim Sentence requiring a check
Source Official page or approved document
Date When it was reviewed
Scope What the source establishes
Publication permission Whether linking or quotation is appropriate

This is particularly useful in bilingual publishing. Both versions should preserve the same evidence boundaries even when the source itself is available in only one language.

What if a source cannot be found?

First ask whether the statement is necessary. A decorative statistic can often be removed. If the information is essential, keep it pending in the editorial record rather than publish it as an established fact.

A method preference can be written as a suggestion, but this must not disguise an unverified fact as opinion. “I would test this approach” can describe a choice; it cannot establish an outcome that never occurred.

Include visual sources

Record where a photograph came from, what changes were made and its permitted uses. Separate reference images from publication assets to reduce confusion. I would not add an image with unclear origins to the final package merely because it suits the layout.
