But there are other things to observe. One is that, in spite of the fact that you can find it all (illegitimately) for free, we continue to sell PDFs. Heck, last weekend we offered a discount bundle of the entire Ars Magica 4th Edition line (all of it published before 2005), and netted more than $4000 in a few days. That exceeds the original budget of most of those individual books, including printing.
