Artificial languages are a minor area of linguistics.
There are however a phenomenal number of artificial languages around. Indeed, while natural languages are shrinking in number man-made ones are increasing.

If you want to get a flavour of the variety around try Jeffrey Henning's Model Languages electronic newsletter website. I have given other links below too.
