Ancestry.com recently released some more images of original military records. According to the website, the Ireland Casualties of World War I, 1914-1918 database "contains the book, Ireland’s Memorial Records - an 8 volume set compiled by The Committee of the Irish National War Memorial, originally published in 1923. These volumes provide information on over 49,000 Irish men and women who died in the Great War."
More recent additions include an update to the Australia Cemetery Index, 1808-2007, as well as a new collection of approximately 1.2 million death records -- Paris & Vicinity, France, Death Notices, 1860-1902. The latter "contains death extracts from the historic department of Seine, France from 1860-1902. The extracts were compiled from newspaper and other death notices by ARFIDO S.A., a French genealogical and heir research association. Information extracted includes name of deceased, their death date, and death place." You'll need to know French to adequately search this one.
Also, Ancestry is offering everyone the ability to search their U.S. Military Collection for free through November 13th.
