The second half. I would like to have put them together but the DA upload limit would not allow it. I still have more paper yet but would like to arrange it in some sensible manner before I upload another batch.
As previously stated, you have to download it to see the papers. The paper is free for any use, commercial or personal, provided you don't try to sell the paper itself. In other words it has to be used in some project. You can't sell it as it appears here.
If you submit it here, try to link back to this upload. I won't be a nazi about it, though. I don't care if people don't remember; I just want everyone to have the opportunity to use the papers.
