Lot's of references on this site to Cosmos companion. 

Lot's of questions asking for a copy, or where to find.

I found quite a few PDFs (I don't know for sure if this is all of them) so I zipped them together to share.

The zip file is quite near the max size limit, so in the future if it ever doesn't work (e.g. something on the backend of the forum changes and it breaks the link) please just contact me through the forum and I'll try to re-upload it or host it somewhere else.
