Ancestry's Scottish Electoral Registers

There's a new collection, Aberdeenshire, Scotland, Electoral Registers, 1832-1976 with 3,219,223 records on Ancestry.
Sourced from the Aberdeen City and Aberdeenshire Archives the originals are usually printed and the index based on text recognition software. I did find some early volumes handwritten and available for browsing but not indexed for searching.
Search boxes available are first name, last name, event year, keyword and residence year.
There are no registers for the war years 1916, 1917 and 1940, 1941, 1942, 1943 and 1944.
Information available is typically first and last name, occupation (not found in later years), place of abode, and nature of qualification to vote (also not found in later years).
The collection is indexed for every fifth year, other years require visually scanning images available.

Ancestry has also updated the collection Fife, Scotland, Electoral Registers, 1914-1966 with 1,071,893 entries.
