File of 19th and 20th century Ordnance Survey maps of Aran. Although the items in this file are undated, it is probable these are the early building blocks of Robinson's 1975 map of the Aran Islands. The OS maps have been cut into fragments and heavily annotated, with the Irish language version of each placename written in, local features drawn, corrections and updates added, and some additional features hand-drawn using coloured ink.
There are 7 cut outs in total. Two from OS Map Sheet 110, one from Sheet 111, and four from Sheet 119. These are taken from the 1966 edition of the 6 inch OS map.
Also filed with these maps are photocopies from other reference maps, with annotations. These seem likely to have come later, when Robinson went on to update his mapping. One is a hand-drawn sketch on tracing paper entitled 'Aran areas of small fields 1cm²'.
6pp of Robinson's notes with calculations on the fields in Árainn, giving average perimeters, grids and calculations.
Four copies of sections of the 1839 OS map showing Baile na Sean.

Sheet 113 of the OS 1 inch map of Aran Islands showing Inishmaan and Inishmore. Robinson's calculations drawn in pencil.
