The article is a brief outline of some online (mostly foreign) resources devoted to manuscripts in Arabic, Persian, and Turkic languages from various world repositories and libraries: their digitization, cataloging, and presentation on the Web. These are both the most famous European and American library databases (for example, “Gallica” that is a project of the French National Library/ Bibliothèque nationale de France, or Virtual Hill Museum and Manuscript Library, USA), as well as the project of the Istanbul University Library (the final digitization of the material was completed in May 2021), and some Russian resources (“Manuscripta Islamica Rossica” and the project of digitalization of the Fund of Oriental Manuscripts of the Institute of History, Archeology and Ethnography of the RAS in Dagestan). One of the most important sources of digital copies of Persian manuscripts is the Malek Library (Iran), which provides free online access to digitized manuscripts and documents. Specialized resources that are devoted to any one aspect of the study of the arabographic manuscripts are of particular interest: these include a database dedicated separately to the seals of Muslim manuscripts, which is being developed by the Chester Beatty Museum and Library (Dublin), as well as a digitized collection of Arabic manuscripts from the Wellcome Library (London), which relates to the history of classical medicine in the Muslim world.

In our review, we did not include repositories whose collections are digitized, but are not publicly available online (despite the fact that they are among the most important in their field).
