Ancestry adds UK Medical Directories

Several years ago browsing in the Wellcome Library in London I came across a hoard of medical directories  Ever since I've wondered when they'll be online. Now Ancestry has digitized them and placed them in the Schools, Directories & Church Histories category. The collections, which have a few year gaps in coverage and can be searched or browsed, are:

UK & Ireland, Medical Directories, 1845-1942, 738,852 records
UK, The Midwives Roll, 1904-1959, 398,334 records
UK, Physiotherapy and Masseuse Registers, 1895 -1980, 128,037 records
UK, Dentist Registers, 1879-1942 Schools, 124,647 records
UK, Medical and Dental Students Registers, 1882-1937, 92,436 records
UK, Roll of the Indian Medical Service, 1615 -1930, 8,443 records

You can search by name and also by place, which includes locations outside the UK.
The records usually include names, address, date first registered, and qualifications (postnominals).

These directories are a great resource for those pursuing a one-name study.
