In most cases we have obtained permission to digitize the text(s) from the authoritative agencies/publishers/individuals and provide open access to the texts through this repository. If the agency is not recorded or otherwise the case may be, either such an authority is not mentioned in the printed book or the rights holders did not respond to our frequent letters; and we consider that the document is rare, out-of-print and should be preserved. All queries regarding such documents may be addressed to sba@azimpremjifoundation.org. Also, we have archived public domain books which are of interest to this project.
