The Scottish National Dictionary Association (SNDA) was founded in 1929 to foster and encourage the Scots language, in particular by producing a standard dictionary of modern Scots. This primary aim was fulfilled in 1976 with the completion of the 10-volume Scottish National Dictionary (SND), covering the language from 1700 to 1976. Material for SND is drawn from a wide variety of written and oral sources of Lowland Scots from Shetland to Ulster. SND was produced under the editorial direction of William Grant (from 1929 to 1946), and of David Murison (from 1946 to 1976).
After the Scottish National Dictionary was completed, with its Supplement, in 1976. The Association went on to produce the Concise Scots Dictionary (1985) under the leadership of Mairi Robinson. In 1986 Iseabail Macleod became editorial director, and the SNDA went on to produce a wide range of smaller Scots dictionaries, including the Scots Thesaurus (1990). The Association also established an ongoing Word Collection in order to create a constantly updated resource on modern Scots.
In 2002, when the related Dictionary of the Older Scottish Tongue Project reached completion, a new organisation, Scottish Language Dictionaries (SLD) was formed to further Scottish lexicography. Building on the work of The Scottish National Dictionary Association and the Dictionary of the Older Scottish Tongue, Scottish Language Dictionaries Ltd is a charity and Limited Company.
