Material Wealth: Mining the Personal Archive of Allen Ginsberg is a 2023 book by countercultural historian Pat Thomas.

A prolific poet, raconteur, activist, and thinker, Allen Ginsberg was also a prolific collector, meticulously saving letters, postcards, draft notes and manuscripts, photographs and snapshots, appearance bills and rally broadsheets, not only featuring him personally, but also his fellow poets, singers, lovers, writers, journey companions, friends, and agitators. Gathered here publicly for the first time is his personal archive of events and experiences documenting his life as a young man, breakaway poet, expansive spirit, curious intellectual traveler, and relentless enthusiast of the provocative and the profane.
