ABOUT
About this site
IT History is a curated chronicle of the moments when computation rewove the world — published as editorial long-form across timelines.
Operator
IT History (history.itlibra.com) is one of the web properties run by itlibra, an independent operator of editorial and tooling sites.
Editorial methodology
This is a chronicle of moments, not a list of events. Each entry asks three questions — why did this happen, what changed, who drove it — and answers them in long-form prose.
Events are ranked Tier 1 / Tier 2 / Tier 3. Tier 1 items get dedicated articles of 800–1,500 words with multiple cited sources. Tiers 2 and 3 are timeline-only summaries; they get promoted to Tier 1 as the article is written.
Sources
Every Tier 1 article must cite at least one source. Sources appear at the foot of each article with title, URL, access date, and a primary/secondary/tertiary tag.
Images come exclusively from Wikimedia Commons under Public Domain, CC0, CC BY, or CC BY-SA. Author, licence and Commons file URL are credited under each hero image. No fair-use imagery is used.
AI involvement
Most article bodies are drafted with the help of large language models — primarily Anthropic Claude. Operating rules:
- Every claim is verified against a primary or secondary source via web search before publication.
- Sources are listed inline so claims can be checked.
- Uncertainty is flagged in the prose ("multiple accounts exist", "exact date unknown").
- An editor reviews the draft before publication and fixes errors or one-sided framing.
We do not hide AI authorship; we frame the site as a modern chronicle produced by humans and machines together.
Languages
Published in Japanese (/ja/) and English (/en/). Japanese is the primary locale (x-default); English is a translation. Translation quality varies; the primary language can differ per article.
Monetisation
The site is funded by Google AdSense auto-ads. Ad placement is automatic only, to avoid hurting reading. See our privacy policy for how reading data is handled.
