I've put a link on the front page on my invertebrate site to a free ebook I've made on the characteristics of the various invertebrate phyla.
This is the first ebook I've made, and if it is a success I'll do more.
I've recently acquired a Kindle, so have been exploring the possibilities of the medium.
Now I'm off to prepare myself and house for Hogmany - the most important time of the year.
Lang may all your lums reek!
