The new issue of Typography papers (no. 4), published by the Department of Typography & Graphic Communication, University of Reading contains an article by Peter Burnhill, ‘Type spaces’, and a symposium on these ideas. This is the first presentation of his research into the typography of Aldus Manutius. Burnhill finds a unified system of dimensions to be present there, as both a physical and a syntactic structuring device. A group of designers then respond to this thesis. We plan to publish Burnhill’s work fully, as a book. Meanwhile, readers are urged to get hold of this interim publication.
