Well, it's that time again, December 25th, which those of you who've been around here long enough will know as Mindat's birthday. I started the mindat project as a personal database on December 25th 1993, so Mindat is now 15 years old! The website was launched in September 2000 based on the earlier database project.

As a special gift, I have a very exciting new free book download to offer you - Rudy Tschernich's book Zeolites of the World - which is now available as a FREE download by clicking on the link below.

Note that the file is 237Mb! so you WILL need broadband and some patience to download it.

MANY thanks to Ric Delmonte for scanning everything in, and of course to Rudy for giving us permission to distribute his book, which is the definitive reference to the zeolite group.

If people don't have broadband or would prefer to purchase a copy on CD, I can do this for a nominal amount plus postage costs - I'll post details of this in the next few days.

Note. I have updated the book with some missing introductory pages and title page - so if you have a fast connection and downloaded it previously, you might want to download the new revision.
