The Guerilla Clinic was an informal, "underground" group of AIDS activists who obtained unapproved, experimental drugs (mostly from Mexico) and distributed them at cost to PWAs who wanted them. This carton of records was produced and/or compiled by Blaine Elswood, who donated them to UCSF's Special Collections in 1990. Elswood was a founder and major activist of the Guerilla Clinic.

Most of these files involve the drug Dinitrochlorobenzene (DNCB). During the mid 1980s, DNCB was being used by some PWAs as a topical treatment for Kaposi's Sarcoma. Elswood had personally benefitted from using it, and talked to other PWAs and a few providers who believed there was sufficient evidence to warrant legalization, or at least testing, of this promising drug. He fought a long and hard battle with the medical establishment to bring attention to, and stimulate research on, DNCB as a treatment for KS. By 1987 Elswood, with the encouragement of Dr.Donald Abrams, began to draft an FDA Grant for DNCB Study. This grant was submitted and approved in 1988.

The original donation consisted of two cartons of records; this was narrowed to one carton during arrangement. Removed were numerous duplicates, envelopes (return address and mailing date were noted on enclosures when needed), general AIDS pamphlets and reprints, and the following three books:

A number of personal items belonging to Blaine Elswood have been kept, including his passport, desk calendar and daily schedule books, and records related to his employment. All are related to the Guerrilla Clinic. One booklet that isn't directly related was retained; this is the self published In the Heat of Passion by ex porn star Richard Locke. Locke spoke, taught, and wrote about safe sex - insisting that people could and should enjoy a healthy sex life while maintaining a vigilant "safe sex only" standard. This copy of his booklet is signed to Ellswood by Locke. Two audio cassettes and three videotapes (VHS format) were also donated to UCSF's AIDS Video Collection.
