The Arcanum SRD v0.1 is done. You can find it here on the website.
The Bestiary chapter is a long one and will get a separate file all its own. Additional material that is developed and written will get additional SRD files for them as well. All of them will be available on the Arcanum SRD page (see the menu at the top of this site for the link).
Note: the first copy I uploaded had an error in it that causes text to overlap tables on two pages. A new version has been uploaded that corrects this error. Sorry for any inconvenience.
