Brian was made an Honorary Member of the Charles Close Society in 2005.
Brian's research papers, together with his associated maps and books have now been deposited in the Charles Close Society Archives
The collection contains two overlapping bodies of material, reflecting his work with Hydrographic Department, then as a private researcher into Ordnance Survey mapping (1980-2005) - his collection of source books (a mixture of original volumes and photocopies) that supported his research, as well as what survives of his research papers. Most of the work he completed, both published and unpublished, has been gathered together in the volume Projections and Origins. Fundamental to all this are Brian's private note books containing his "computations". Some material is held on other subjects which interested him, such as lettering styles of the Ordnance Survey, meridian marks, administrative areas. His important collection of railway system diagrams and papers relevant to his railway interests are held by the Map Department of Cambridge University Library.
