A few days ago I wrote that the proceedings of the 15th International Congress of Speleology were posted as three PDFs on the Karst Information Portal (KIP) at
Each PDF is for each volume of the proceedings. I wrote that the files were large, 11, 16, and 18 Mb for volumes 1, 2, and 3. Now they are much larger: 86, 153, and 155 Mb. The earlier files were compressed and the quality of the figures was poor. The figures now look excellent in the new PDFs. I apologize for any inconvenience.
As a reminder, you can buy printed copies of the proceedings from the NSS Bookstore at http://nssbookstore.org/index.php?mode=store&submode=showitem&itemnumber=04-0106-2378 .
Also for a limited time you can get a fun cowboy boot drinking cup for free when you order the proceedings. These were very popular at the International Congress. Just include the words "COWBOY BOOT" with your order.
