Web Building Encyclopedia

What it is

A cited reference on how the web was built: its technologies, people, machines, laws and turning points, from the first website in 1991 to today. Every entry links each fact to a source and ends with what the subject means for your website.

How the encyclopedia is written

Entries are written from primary sources: the projects' own documentation and release histories, standards documents, court and government records, and first-person accounts. Every date, number and name links to a numbered reference we opened, with the date we checked it. A separate pass that did not write the entry checks each fact before it is published.

Entries are neutral. Where sources disagree, both sides are shown with their sources. Each entry carries a review date, and fast-moving subjects are re-checked every six months.
