ScotlandsPlaces provides a search across three national databases to access historical resources relating to places throughout Scotland. It is particularly useful for places which are problematical in some way, e.g. due to boundary changes. It also has links to other gazetteers. Hay Shennan (see below) provides information on the boundary changes that took place in Scotland in 1889.
County and Parish Boundary Changes, 1892
"Boundaries of Counties and Parishes in Scotland", by Hay Shennan, published by William Green and Sons, Edinburgh, 1892. Information on the boundary changes that took place in Scotland as settled by the Boundary Commissioners under the Local Government (Scotland) Act, 1889. Such changes affected the boundaries of counties, parishes, and burghs.
The link above provides access to images of the changes recorded for each county and parishes therein, e.g Lanarkshire.
