Editorial policy

PrinterArchive is written to a conservative editorial standard. Its aim is not to be exhaustive, novel, or surprising; its aim is to be correct, sourceable, and durable. Where that goal forces a slower publication pace or a quieter claim, that trade is accepted.

Conservatism principle

The archive prefers to describe a mechanism precisely rather than assert a figure, date, or attribution it cannot stand behind. Where a claim depends on a specific source, that source is cited. Where the underlying historiography is contested or uneven, the entry is organised around the operational character of the technology — what it did, what it cost, what it changed — rather than around a single datable sequence. The recurring "A note on dates" callout used throughout the history cluster is the visible artefact of this rule.

Sourcing standards

Entries draw on institutional archives, peer-reviewed material, primary sources where available, and well-established encyclopedic references. The full allowed-source set, and the equally important forbidden-source set, is documented on the source policy page. Each entry that carries external claims surfaces its references in the Source transparency block at the foot of the article, where the reader can inspect them without leaving the page.

Attribution methodology

Every image in the archive carries an explicit source, a license string, and a link to the descriptor page on the institution that holds the original. The build pipeline enforces this with a content-integrity gate that fails the build if any image lacks alt-text, dimensions, source, or license. Attribution is recorded verbatim as the source institution provides it; the archive does not paraphrase or shorten institutional credit lines.

Correction policy

When an entry is found to contain a factual error, an unsupported claim, or a mis-attributed image, the correction is made directly to the entry and the entry's updated date is advanced. Significant corrections — those that change the meaning of a claim rather than fix a typo — are also noted in the changelog. Editorial questions and corrections can be sent to info@helperg.com.

No AI-fabricated history

The archive does not publish AI-generated historical imagery, fake retro recreations, or invented bibliographic citations. Machine-assistance is used in drafting and copy-editing, but every factual claim and every cited source is reviewed and verified by a human editor before publication. Entries that cannot be sourced honestly are not published.

Editorial cadence

Updates are made deliberately rather than continuously. Entries are revisited when new institutional sources become available, when reader corrections require it, or when adjacent entries surface a contradiction. The archive prefers fewer, more durable entries to a rapidly-expanding catalogue of unstable ones.
