A tournament that publishes its complete results archive is doing something optional. The reasons are commercial and institutional rather than antiquarian.
An archive is a claim to continuity
A long unbroken record is an asset. It establishes that the event is the same event across decades, which is much of what tournament prestige consists of.
Publishing it makes the claim verifiable. Anyone can trace the line of champions, which is a stronger assertion than simply stating a founding date.
Events without such records cannot make the claim in the same way, regardless of how long they have run.
Publication controls the narrative source
If a tournament does not publish its own record, third parties compile one, and their version becomes the reference that journalists and broadcasters use.
Third-party compilations contain errors and make their own inclusion decisions. Publishing authoritatively means the tournament's version is the one that circulates.
Correction also becomes possible. An event that publishes its own record can amend it when a researcher finds an error, which it cannot do to someone else's database.
This matters for edge cases: which events count as part of the championship's history, and how wartime interruptions or format changes are represented.
What gets included is a judgment
An archive has to decide whether to include qualifying, junior and invitational events alongside the main draws, and whether to present them at the same prominence.
Those choices determine what appears in a player's tournament record, which in turn determines how careers are described.
Including everything is not obviously right, since it can bury the main competition. Excluding is not neutral either, since it erases participation.
Depth is limited by the historical source
Modern years can be published with point-level detail while older years offer only results, so the archive is uneven by necessity.
Presenting both in one interface risks implying comparability that does not exist, which is why well-built archives mark the boundary explicitly.
The alternative, publishing only what is uniformly available, would discard almost everything the modern record contains.
Why the maintenance never stops
Archives require continuing work: correcting errors found by researchers, adding newly discovered sources, and migrating formats as technology changes.
Format migration is the underrated risk. A digital archive that is not actively maintained becomes unreadable faster than paper deteriorates.
An institution publishing an archive is committing to that maintenance indefinitely, which is a larger undertaking than the initial publication.
