Special Collections & Archives holds a variety of town guides from cities across the UK. Most significant urban centres in the British Isles are represented, and there is a comprehensive collection of guides to places which became Greater London in 1965.

The guides can provide a benchmark for assessing the very substantial changes which have affected British urban places in the past 60 years, and may be of interest to researchers in a variety of disciplines.

The town guides vary in size from a slender brochure of 30 pages for a small Urban District to large-format volumes of over 300 pages for a major City and County Borough such as Liverpool.
