The portal Grand Mémorial is part of the website Culture, the main portal of the French government for information about and research in French cultural institutions. At least thirty French archives contribute to the Grand Mémorial. The main aim of this portal is to help genealogical research, The website gives quick access to several databases, more precisely for unit diaries (journaux des marches et opérations), regimental registers (registres matricule) kept at the French regional archives (archives départementales), information about soldiers killed in action (Morts pour la France) and their graves (sépultures), war monuments as provided at Mémoire des hommes, and also La Grande Collecte, a crowdsourcing project for documents and memorabilia, an initiative of French archives. There is a simple search mode for finding people with their name and family name, and an advanced search mode with more filter options (date, department, country, source, etc.). The Grand Mémorial portal can be searched in French, English and Spanish; the background information is given only in French.
