Mindat's 15th Birthday and a present for everyone

Last Updated: 28th Dec 2008

By Jolyon & Katya Ralph

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.

Click here to download (237Mb)

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.

Article has been viewed at least 33345 times.


Jolyon..Your a great guy with a great site, thanks for all you've done!
Happy 15th birthday for this wonderful site!

Normally we give presents to the birthday-boy... Thanks for the zeolite-book, Jolyon!
Please keep it up! We would be lost without your site.

Happy holydays and thanks again

Mindat is a fantastic service for all mineralogists, and I take my hat off to you! Thanks also - to you and to Ric and to Rudy - for making this excellent book available. My download took a little longer than Roy's but that's not a problem.
I wish you a very peaceful and prosperous 2009.

Far too late, but with many thanks !
A wonderful book and a 'must have' in every mineral collection.
So much better than a turkey or a Guinness....

Congratulations and a Happy New Year!
Keep on this good work (and presents)!

Just started downloading the .pdf (35% as we speak).
Great idea for an anniversary gift, thank you very much and Happy Anniversary to Mindat, Jolyon and the exceptional mods.
If i've said it once I've said it a thousand times...
Mindat is an incredible achievement not only for Jolyon with his foresight and dedication, but for the many, many people who have taken the site to their hearts and helped to produce a most amazing resource unequalled in any field as far as I can tell.
Thank's again, for everything (57% and counting :) )
