an official from another state at the conclusion of the meeting. Prepared in advance, it contains a short summary of the main points addressed by the visiting official during the meeting and, firstly, serves as a memory aid for the visiting official when speaking. It, secondly, removes ambiguity about the subject of the meeting occasioned by verbal miscues by the visiting official. Bouts de papier are always presented without credit or attribution so as to preserve the confidentiality of the meeting in case the document is later disclosed. Démarches and aides-mémoire A démarche (non-paper) is considered less formal than the already informal bout de papier. Officially described as "a request or intercession with a foreign official" it is a written request that is presented without attribution from the composing state and is, therefore, delivered in-person. Similar to a démarche, an aide-mémoire is a proposed agreement or negotiating text circulated informally among multiple states for discussion without committing the originating delegation's country to the contents. It has no identified source, title, or attribution and no standing in the relationship involved. Protocol Standard diplomatic protocol varies from country to country, but generally requires clear yet concise translation between both parties. Language The earliest forms of diplomatic correspondence were, out of necessity, written in Latin, Latin being a common language among states of a linguistically diverse Europe. By the early 19th century French had firmly supplanted Latin as the language of diplomacy; on one occasion, in 1817, the British attempted to correspond with the Austrian Imperial Court in English, prompting Klemens von Metternich to threaten retaliatory correspondence in Weanarisch. In modern times, English has largely replaced French as a diplomatic lingua franca in correspondence between two states lacking a common tongue. Rejection States may sometimes reject diplomatic correspondence addressed to them by returning the original copy to the sending state. This is done as a rebuff of the contents of the correspondence and is typically reserved for cases where the receiving state feels the language used by the sending state is rude, or the subject matter represents an inappropriate intercession into the receiving state's internal affairs. Publication Diplomatic correspondence has been published in the form of color books, such as the British Blue Books which go back to the seventeenth century, the German White Book and many others from World War I, partly for domestic consumption, and partly to cast blame on other
