This catalog links to a PAYPAL shopping cart. You do not have to be a Paypal member to make a credit card purchase. 

If you do NOT wish to use PAYPAL, you may also pay with a money order payable in $US, but please notify us by email before you do.  The email address is displayed in the shopping cart.

Please do not send personal checks. Send cash in $US at your own risk (but its probably safe, at least at this end).

A shipping/handling charge of $3 is added to each order, regardless of the number of items purchased.  Our desire is to make these CDs and DVDs available worldwide,
so there is no added charge for shipment outside of the U.S. 

Items will be shipped
first-class in North America, and airmail outside of North America. Shipment will be made as soon as possible after receiving payment. If there is any delay (to make additional CDs, for example) we will notify you immediately by email.

Satisfaction is guaranteed, and we will replace defective items, or refund payment if you notify us within a reasonable time (30 days seems reasonable to us) with the reason for your dissatisfaction.

You can check your shopping cart at any time by using this link:

You can change quantities, delete items, and do final checkout from the Shopping Cart.

You are not committed to complete a purchase or provide any personal information until the final checkout.

The Collection of HMS Challenger reports is available  in both CD and DVD format.

The CD reports contain the text pages at 100 ppi, to conserve space and facilitate download. Plates are at both 100 ppi and 200 ppi. Maps and charts are at resolutions up to 600 ppi.

The DVD reports include the contents of the CD reports plus the text pages at 400 ppi (to use with optical character recognition software), and copies of the original (trimmed but otherwise unedited) page photographs.  The original copies can be used to re-process pages (improve rendition, color, contrast, etc.)

This is the first complete compilation of the H.M.S. Challenger reports in an electronic format, and it is expected that improvements in quality will be made over time.


The Backup DVDs are a complete collection on 12 data DVDs. They can be purchased as a complete collection or as individual DVDs.

DVD-1 includes  the folder HMSC-INDEX, which contains both a linked index (to access the reports) and an illustrated index. The -README htm provides access to the indices and reports.

To browse the entire collection of H.M.S. Reports and books, the contents of all of the DVDs should be copied to a hard drive, requiring about 52 gigabytes of disk space.  To browse part of the collection, the contents of DVD-1 and other DVDs containing the desired reports should be copied to a hard drive. Any reports that are not copied will appear in the linked index as broken links, but otherwise the index will work normally.
