The following files have been added to the premium ShipIndex.org database in the past few days:

• Bonner-Smith, D., and E. W. R. Lumby. The Second China War, 1856-1860 (Navy Records Society, Vol. 95). London: Navy Records Society, 1954.
• Canney, Donald L. The Old Steam Navy: Frigates, Sloops, and Gunboats, 1815-1885 (The Old Steam Navy, Vol. 1). Annapolis, Md.: Naval Institute Press, 1990.
• Merriman, Reginald Dundas. Queen Anne’s Navy: Documents Concerning the Administration of the Navy of Queen Anne, 1702-1714 (Navy Records Society, Vol. 103). London: Navy Records Society, 1961.
• Pickford, Nigel. The Atlas of Shipwrecks & Treasure: The History, Location, and Treasures of Ships Lost at Sea. London & New York: Dorling Kindersley, 1994.

The last one listed describes shipwrecks around the world. A correspondent suggested that we add more content surrounding shipwrecks, which I thought was a great idea. This is a start. I understand that there are a number of diving guides regarding shipwrecks, specifically intended to help divers locate particular sites. I’d love to know more about those, and get some examples from folks. If you have any ideas about such items — either books or websites or other sources — please let me know by email or in the blog comments section below.

Thanks.
