Retcon article
(covers information that was retroactively changed)

The Daystrom Institute Proceedings was a periodical published by the Daystrom Institute in the 24th century.

Lieutenant Commander Data, while in command of the USS Sutherland, read Vol. CXCV, No. 47; Vol. CXCIX, No. 20 and Vol. CXCVI, No. 30 of the proceedings on a viewscreen while searching for clues on how to detect cloaked Romulan warbirds during the Klingon Civil War in 2368. (TNG: "Redemption II")

For the remastered episode, the text for the graphics was altered, and this periodical was "retconned" from the episode.
