Work for the series Placenames of the Isle of Man is undertaken under the auspices of the Manx Place-Name Survey, set up at the University of Mannheim in 1988. The survey falls into two parts: material collected from a) oral, and b) documentary sources. Placename material, mostly Manx Gaelic, for the first part, was collected on sound-recordings or in phonetic script 1989-1992 from some 200 informants, almost exclusively from the farming community. The second part contains material drawn from documentary sources of 13th-20th century date, but mostly from 17th-19th centuries. The whole is to appear in seven volumes, the first six based on each of the six Sheadings (districts) as follows: Vol. 1 - Sheading of Glenfaba, Vol. 2 - Sheading of Michael, Vol. 3 - Sheading of Ayre, Vol. 4 - Sheading of Garff, Vol. 5 - Sheading of Middle, Vol. 6 - Sheading of Rushen, Vol. 7 - Douglas. The last volume also contains a detailed linguistic discussion of the corpus, a full and comprehensive index, as well as a series of element distribution maps and maps of the 17 parishes showing the traditional land divisions upon which the names are based.
