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.

Sheets 113 and 122 from the Geological Survey of Ireland, showing the Aran Islands and Inisheer at the scale of one inch to a mile. (Published Oct 1862 and Mar 1869).

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

Six folders containing 56 maps, all annotated six inch OS maps. The maps are mainly the 1965 and 1966 editions with a small number from the 1974 and 1978 editions. Some of the maps in this file are photocopies that are sellotaped together. All maps contain edits that mark in additional features and placenames. The file begins with a fragment of the Ordnance Survey sheet index for Co Galway, with Robinson's handwritten notes listing the sheets he will require for his mapping project.
