The Hiteshranjan Sanyal Memorial Archive is a huge collection of textual and visual materials mainly focused on colonial Bengal. Starting in 1993, the Centre for Studies in Social Sciences, Calcutta (CSSSC) has undertaken the task of microfilming and digitising a huge amount of textual sources, including all the major journals of colonial Bengal. This unique collection also extends to rare Bengali books, Assamese journals and books, as well as visual art and popular culture (such as specimens of historical Bengali advertising).

As part of a Memorandum of Understanding between the CSSSC and the South Asia Institute of Heidelberg University, the textual part of this collection has been made available on the FID4SA Repository. It is hoped that this will be an important step towards facilitating access to these materials and thereby stimulating further research.
