At least some of the editions of the Indian Army List have been uploaded by the Digital Library of India to the Internet Archive, Archive.org. The download options appear to be pdf files, (which is what is available on the Digital Library of India), and in addition a Torrent download, which I understand may also be called BitTorrent, but I am otherwise unfamiliar with this type of download Some other books uploaded by the Digital Library of India to Archive.org you can read online, but this option was not available for the (small number of ) Indian Army Lists I looked at. Cheers Maureen Edit: It is possible that the the ability to read the book online may be a feature which appears in the next dew days, as these books have only been uploaded quite recently. 2nd edit 1 April 2017: Some editions are now available to read online. At the current rate, it could be mid 2017 before this feature is available for all editions. Full range of Internet Archive download options appear to be now available.
