The archive

Corrections policy

Any reference work of this size contains mistakes. What matters is whether they get found and fixed. This page explains how to report an error, what happens after you write, and how corrections are recorded on the entries themselves.

Last updated September 2, 2026

A timeline spanning nearly a century of technology, business and culture will get some things wrong. Dates get transposed. A company is credited with a machine it only distributed. A figure with no documentation behind it slips through because it appears everywhere else. None of that is acceptable, but pretending it never happens would be worse. The archive treats correction as ordinary maintenance rather than as an embarrassment to be managed.

How to report an error

Write to corrections@maticpayu.com. A short message is fine, and no particular format is expected. These details make a report much easier to act on:

  • Which entry or page you are writing about, by its title or the period it sits in.
  • The specific sentence or claim you believe is wrong, copied into your message.
  • What you believe the correct version is.
  • Where that comes from: an archive record, a filing, a court document, a book with a page number, or coverage published at the time. A source is not required, but it moves things along considerably.
  • Whether you are speaking from firsthand experience, which is treated as evidence and checked in the same way as anything else.

What happens after you write

Reports are read by a person. The claim is taken back to the sources cited in the entry and to whatever new source you supplied, and the check is carried out by someone who did not draft the entry. If the entry is wrong, it is fixed. If your source and the existing sources conflict, both are weighed against the sourcing hierarchy in the editorial policy, and the entry may end up describing the disagreement rather than asserting either version.

How long it takes

The archive is maintained by a small team, so no response deadline is promised here. A promise of that kind would be worth very little. Clear factual errors with a source attached are handled first, because they are quick to verify and the most damaging to leave standing. Reports that require archival work can take considerably longer, and a few stay open because the documentation needed to settle them does not appear to exist. Not every message receives an individual reply, but every message is read.

Three different kinds of change

Correction
A statement of fact was wrong. A date, a name, a company, an attribution or a figure is changed to match the evidence, and a substantive correction is noted on the entry.
Clarification
The statement was defensible but read as though it meant more than the evidence supports. The wording is tightened, a qualifier is added, or a missing piece of context is supplied.
Matter of interpretation
The sources genuinely disagree, or the question turns on a definition rather than on a fact. These are not settled by preference. The entry is rewritten to present the competing accounts and to say plainly that the point is disputed.

How corrections are recorded

Every entry carries the date it was last reviewed, and that date is updated whenever the entry is checked, whether or not anything changed. Substantive corrections are noted rather than made silently, so a reader can see that a claim was revised. Small repairs that do not change meaning, such as a misspelling or a stray piece of punctuation, are simply fixed. The aim is that nobody has to take the archive's word for its own reliability.

What a correction request cannot do

The archive removes claims that are wrong or unsupported. It does not remove accurate, sourced statements because a company or an individual would prefer they were not there, and it does not adjust historical framing to match a current marketing position. Requests of that kind are read and answered honestly. If the objection is that a sourced statement is incomplete rather than false, that is often a fair point, and the usual outcome is added context rather than deletion.
