Introduction to Ordnance Survey maps
Shropshire Archives does not actively collect sets of OS maps: even so, we hold almost complete coverage at most editions, although we do not necessarily have every sheet published.
Our collection includes negative and some positive paper copies of OS drawings, the earliest OS mapping for Shropshire, undertaken between 1814 and 1817; digitised images can also be viewed on the British Library website ’s online gallery.
The majority of our Ordnance Survey maps, ranging from the 1833 1”:1 mile to 1:1250 1980’s and recent Landranger series, can be found on open access in the Reading Room map cabinets. A good collection of the several editions of the 6” sheets are also available here. A detailed guide and large index sheets can be found on top of the cabinets and there is a source guide on our website. All of the County series 25”, 6” and 1:500 sheets can be found on aperture card in the Reading Room fiche cabinets. Also on aperture card are the 1910 Finance Act maps. Some original 25” and 1:500 sheets and Finance Act maps have survived, and are stored in our basement but may be in poor condition – check with staff if you need to see one of these to view at the original scale.
