Here is the notice -
"In January 2014, we announced a project to digitize 640,000 Canadian Expeditionary Force personnel service files as part of the First World War commemoration activities of the Government of Canada. The goal of this project is to provide free access to high-quality digital copies of all service files in PDF format, anytime and anywhere.
Close to 100 years old, these personnel files are quite brittle. Additionally, over the years, service files have been consulted many times, so they are extremely fragile. It was time to take concrete steps to ensure their preservation for future generations.
To achieve this goal, Library and Archives Canada (LAC) will have to close portions of this collection as they undergo preparation, conservation, and digitization. The entire process is complex because each file must be examined: staples, paper clips and glue must be removed, and in some cases, the files must be treated for mould. After this preparation is completed, digitization is next, starting with box No. 1 and going up. Once digitized, the service files will be stored in a permanent, safe environment. We estimate that 32,000,000 pages will be available online once digitization is finished.
We are happy to inform you that we have started posting the digitized files online. They are accessible via our Soldiers of the First World War: 1914–1918 data base. As of today, 76,330 files are available online. Regular uploads of about 5,000 files will take place every two weeks. All digitized files are searchable by name, regimental number and rank. We will inform you as more digitized files are added to the database.'
