Reference:Primary

Primary verification means verification agaisnt the actual book, magazine, ebook, or other work. A primary verifier should ensure that all metadata is correct, and that insofar as possible it is complete. If some data comes from secondary sources, that should be mentioned in the notes. For an anthology or collection, contents including page numbers (when present) should be supplied. If art attributions are determiend from signatures (as oppsoed to explicit credits) or deduced from style that should be mentioned in the notes.

If adding data to a publication primary verified by soemone else, you should notify the original verifiere on his or her talk page, unless that verifier has indicated otherwise.

If you are changing substantive data (not changing a blank to a non-blank field), it is usually a good idea to ask the verifier in advance.
