The Boundary Remark Books (also called Perambulation Books) in this series are small booklets containing hand-drawn strip maps. They were prepared by the Ordnance Survey to record original information on public boundaries under the provisions of the Ordnance Survey Act 1841. The maps show boundary and related ground features and carry the signatures or marks of the meresmen (local people with knowledge of the parish boundaries) for the parishes on each side of the boundary. The books relate to English, Welsh and Scottish boundaries.
Catalogue entries for this series have been enhanced as part of a re-cataloguing project undertaken between August 2011 and August 2012.
