The Aga Khan Library, London,* has made part of its rare book collection, which includes manuscripts, out-of-print editions and valuable research materials, available to researchers around the world through its Digital Collections platform. Aga Khan Library Digital Collections is an ongoing project that currently hosts over a hundred valuable books from different periods and areas of the Muslim world, which have been carefully digitised, to enable their preservation and display for a global audience. For example, Digital Collections includes a selection of Ottoman books which reveal almost a century of profound transformations in the Ottoman Empire. Starting in the Tanzimat (era of reform), they cover the foundation of the Republic of Turkey and the rise of Atatürk and his social and cultural changes.The launching of Digital Collections represents a significant milestone in the services of the Aga Khan Library, London to promote scholarship on Islam, past and present. These precious materials can now be easily accessed by multiple scholars simultaneously in a format that enables them to easily magnify text and flip through pages without affecting the source material. At present, the Aga Khan Library, London, rare book collection includes more than 1,000 rare titles; a wide range of materials that span the history, politics, customs, and beliefs that have shaped the contemporary global Muslim community. The library also houses a growing collection of over 50,000 current titles, covering a range of subjects on Islam in English, Arabic, Persian, Turkish, Gujarati, and Sindhi, among many other languages.* The Aga Khan Library facilitates teaching and research at the Aga Khan University’s Institute for the Study of Muslim Civilisations, and the Institute of Ismaili Studies, its parent institutions.
