A curated index of 48 corporate memos, handbooks, and books, presented as free to read or borrow.

Landing page captured for the 2026-09-30 issue.

For: Readers researching business and technology history
Worth noticing: Entries span 1909–2025, and the index labels some items as leaked or original PDFs.

Field notes

The index divides its 48 entries into Documents and Books, pairing titles with an author or organization and a year. Its document list ranges from Warren Buffett’s 1957 partnership letters and Tim Berners-Lee’s 1989 web proposal to 2025 deposition material; a “Submit a rare one” link invites additions. The homepage says every item is free to read or borrow, though the extracted page does not clarify what borrowing entails.
