Date 1966-02 · publication Role Context Register (kind of text) Nonfiction Missing element A general definition of technological change, not an analysis of computers or automation. Tier Tier 1. Economist author (Edwin Mansfield; established record as an economist). Conditions General definition; applies 'regardless of its source or form'. Scope and limits The study takes up automation only through the Commission's acceleration question; it gives computers no separate treatment. Meets M01's 'general tools' condition, while its explicit discussion of automation is thin. Matches the cached .txt.

This status does not say whether a person has read any linked passage. Each evidence record above shows how it was checked.

Date. Date of the appendix volume. Checked in a current copy; an archive capture was not available, so earlier bytes are not authenticated.
