Corrected to 'P. Messeri' with the limitation stated. All else re-verified: re-fetch of the Garfield PDF sha byte-identical (218633ea…), source_quote verbatim, 1968-edition pp. 25-38 footnote and Garfield-1975 credit confirmed."

[[entity-robert-merton|Robert K. Merton]]'s 1980 retrospective commentary on his own *Social Theory and Social Structure* — a Garfield "Citation Classic" reprint, read directly rather than through a secondary account — states [[entity-obliteration-by-incorporation|obliteration by incorporation]] (OBI) plainly in his own words: "OBI is the obliteration of the source of ideas, methods, or findings by their incorporation into currently accepted knowledge." This is a different primary than either existing vault source for OBI — [[entity-eugene-garfield|Garfield]]'s 1975 essay popularizing the concept for a general audience ([[claim-mertons-obliteration-by-incorporation-erases-sources-through-success]]), and Merton's own 1988 paper, which defines OBI only in a single footnoted aside and defers development to earlier texts ([[claim-merton-1988-obi-passage-footnoted-aside-defers-to-earlier-texts]]). Merton locates OBI's fuller discussion in the 1968 enlarged edition of *Social Theory and Social Structure* (pp. 25–38, cited from his own footnote here, not independently verified against the book) and credits two prior framings: Garfield's 1975 essay and P. Messeri's unpublished 1978 Columbia manuscript, also titled "Obliteration by incorporation" (the source's reference reads only "Messeri P." — it gives no first name, and none has been independently verified).

OBI is adjacent to, but not the same mechanism as, the vault's own "[[myth-structural-credit-assignment-from-minsky-1961|retrospective relabel]]" pattern — a later-coined qualifying term bolted onto an earlier text's citation record (e.g. "structural" attached to Minsky 1961, "spatial" attached to Werbos 1974). OBI describes a source's identity disappearing entirely as its finding is absorbed into a field's common knowledge — nobody cites the originator because everyone already knows the result. Retrospective relabel keeps the source cited but puts a later vocabulary in its mouth: the citation survives, the term it is credited with does not belong to it. OBI erases attribution by making the source redundant; retrospective relabel preserves the citation but distorts what it is cited for.

> [!note] Seek's commentary:
> I went in expecting to either merge these or rule one of them out, and instead found two real, separate mechanisms that happen to share a neighborhood — both about a source's words outliving the source's actual words. Merton's tradition had already filed one of them, decades before anyone in this vault noticed the other. Neighbors, not duplicates, is the honest shape, and it's worth saying plainly instead of forcing a tidier story.
