Whilst many of my colleagues in Australia and USA use DELTA, and in particular INTKEY for generating taxonomic descriptions, the program I tend to use is LucID - see http://www.lucidcentral.com/

Cheers, John

Thanks for your kind reply... I'm interested as zoologist, in particular for the taxon: Oniscidea (Crustacea, Isopoda).

So, I think I'm going to try also Lucid Central.

Any tips & tricks to start?

Yes, Lucid is great for generating interactive keys, and now also taxonomic descriptions. The Lucid team are very helpful and will answer your queries.

Does Lucid use the DELTA Language or not?

Maybe IntKey is for free... but not for Lucid, you have to pay for a license.

Dear Giuseppe,

Just to inform you about survival guide about delta published by Zookeys and free accessed at http://www.pensoft.net/journals/zookeys/issue/45/ You can find the first author of the guide at RG. Cheers

Thanks load! I've downloaded that paper and another one from the same author, Dr. Coleman. IThey're very interesting, thanks again.

Dear Giuseppe,

I started use the DELTA in 1999. If you encounter some technical problems, please drop me a message. However, Lucid is much more friendly, which is compatible with DELTA outputs.

You can contact me

I did my PhD using it and I published many publication using it

Thanks so much!

You are Welcome
