Several years after becoming a professional librarian in 1972, I became involved in mail art. This international network of cooperating artists has expanded my vision of both the world and my profession. Over the years, I have taken it upon myself to document various activities in mail art, which would have remained unexamined without the involvement of someone who was both an active participant in the medium and the possessor of professional research skills. In so doing, I have been able to integrate two important facets of my life.
