National languages not covered by an authoritative language academy typically have multiple style guides—only some of which may discuss sentence spacing. This is the case in the United Kingdom. The "Oxford Style Manual" (2003) and the Modern Humanities Research Association's "MHRA Style Guide" (2002) state that only single spacing should be used. In Canada, both the English and French language sections of the "Canadian Style, A Guide to Writing and Editing" (1997), prescribe single sentence spacing. In the United States, many style guides—such as the "Chicago Manual of Style" (2003)—allow only single sentence spacing. The most important style guide in Italy, "Il Nuovo Manuale di Stile" (2009), does not address sentence spacing, but the "Guida di Stile Italiano" (2010), the official guide for Microsoft translation, tells users to use single sentence spacing "instead of the double spacing used in the United States".
