Sorry, I must not have been reading closely enough. Please feel free to print it and save it as a PDF. Heck, use Google Docs copying features to copy it to your own drive if you like and customize them for your needs. These world write-ups are freeware as far as I'm concerned. Meant for the Traveller community to read, download, and enjoy. I'm extremely flattered that people are using them.
I am duplicating them from time to time in the adventures I've been publishing on DriveThruRPG. Gratuitous self-serving plug time:
The Tktk write-up is featured in the library data section of "The Tktk Convergence" for sale here:

and
The Yeróilra write-up is featured in "Iron Spine" for sale here:

The world write-ups look a little classier in Mongoose's adventure template if I do say so myself.
I'll be writing an Oghma write-up soon and publishing an adventure on DriveThruRPG to go along with it. The adventure will be usable as a standalone story or can be inserted into your Drinax campaign if you so desire. I'm also writing what I consider to be an ambitious safari-ship based Solomani Rim campaign, also to be published on DriveThruRPG, but that one might be a few months off.
