Hi Nicolas, > This thread is definitely targeting William and Rob :-)
I just checked and now I see the bulls-eye on my back. So my linear algebra textbook sells around 100 physical copies per year right now. I am less than satisfied with my print-on-demand supplier as they have made marketing the book even harder than my own lack of skill in that department would indicate. Before Amazon shut down their "Honor System" payment service, I would regularly receive donations (usually around $5 each) through that avenue. (If anybody knows a good system for international donations/micro-payments by credit card, besides PayPal, I would dearly love to hear about it. So far Dwolla is not working out for me.) I hope to make some changes in the next 6 months that will translate to more purchases, just so I can provide appealing answers to queries like this one. Website for the book gets about 300 visitors a day, closing in hard on one million page-views lifetime. [1] Tom Judson's abstract algebra book [2], which I am very involved with, sells as a very attractive hardcover on Amazon for about $20 (~400 pages). This is arranged easily through the more professional print- on-demand service Lighting Source International [3]. There were some quality control problems this fall, but hopefully those have been resolved. This was all arranged by Lon Mitchell - a nice illustration of the advantages of *not* using a non-commercial clause on a book. I will see if I can get sales figures from Lon, and communicate that to you (on- or off-list). That's most of what I know. Evolving essays on the subject at [4].
