Research method
The archive is built from 15 research streams (33 working files), each a primary-source-cited investigation of one slice of vintage Coach. Streams A–K were online-sources sweeps; L–Q are catalog deep-reads against a user-supplied corpus of 107 Coach catalogs spanning 1960–2020.
Working notes are in the public repo at
research/. Each stream's findings
flow into the model, designer, authentication, and history entries
that cite them.
A Free online sources
The starter sweep: every reputable online source on vintage Coach, tier-graded.
B Company history and timeline
Coach's history from the 1941 Manhattan founding through the 2001 Signature C launch, every event source-tagged.
C Bonnie Cashin
Cashin's 1962–1974 contracted tenure: turnlock invention, hardware patents, design canon — and the folklore traps.
D Model canon
The full-roster cross-check: every silhouette known from catalog evidence, with style numbers and date ranges.
E Authentication primary data
Per-feature authentication data: creed evolution, hardware, hangtags, country marking, the 12-SPI primary anchor.
F Catalogs and ads online
Catalog and print-ad sources before the user-supplied catalog corpus arrived (preempted by the L stream).
G Coach S-1 / IPO documentation
SEC EDGAR investigation of the October 2000 IPO and the Sara Lee divestiture sequence.
H USPTO trademark and patent
Trademark registrations and Cashin/Coach turnlock patent records — primary IP-document anchoring.
I Coach Inc. fiscal 2003 10-K
The first user-supplied Tier-1 primary source. Anchors: 1941 founding, July 1985 Sara Lee acquisition, Oct 2000 IPO, July 1999 Jacksonville consolidation.
L Original Coach catalogs, 1960–1989
The user-supplied catalog corpus arrives. 1960s–1989 readings, with 1985 and 1989 quarterlies being the most-cited primary anchors in the archive.
M Catalog deep-readings (post-1989)
Year-by-year deep readings continuing from L. M1–M4 cover the 1985–1998 transition window where the most disputes resolve.
N Catalog deep-readings, 1981–1984
Pre-Sara Lee Cahn-era catalogs: brand voice, model continuity, the four-year window before the 1985 acquisition.
O Catalog deep-readings, 1986–1990
Late-NYC peak: 1986–1987 quarterly cadence, 1988–1990 transition. Where the heritage-rhetoric voice solidifies.
P Catalog deep-readings, 1992–1994
Sub-collection diversification: Soho, Sheridan, Berkeley, Continental. P3 covers the full 1994 cycle including the Soho rename.
Q Catalog deep-readings, 1999–2002
