The Ron Heisler Collection was another joint project between the Institute of Historical Research and Senate House Library (part of the Radical Voices season), to produce an online exhibition of digitised front covers of a tiny selection of the extraordinary collection donated by Ron Heisler, trade unionist and lifelong socialist.

The resource includes the front covers of roughly fifty pamphlets from all manner of organisations, dating from the late 18th to late 20th centuries, and covering a vast variety of topics.
