The Recueil des Historiens des Croisades (trans: Collection of the Historians of the Crusades) is a major collection of several thousand medieval documents written during the Crusades. The documents were collected and published in Paris in the late 19th century, and include documents in Latin, Greek, Arabic, Old French, and Armenian. The documents cover the entire period of the Crusades, and are frequently cited in scholarly works, as a way of locating a specific document. When being quoted in citations, the collection is often abbreviated as RHC or R.H.C..
Images of the documents can be viewed in some major libraries. The 1967 reprint of the entire collection by Gregg Press can also be found in major libraries, and there are also full-text PDF files available online, which have been made available by the Bibliotheque Nationale de France Gallica project. Documents can be downloaded in their entirety, or stepped through page by page, with both the original text, and a French translation.
