The price of information
I just ordered an article on .pdf from Eric Document Reproduction Service. The moment I had registered as a customer, I could download the .pdf I wanted, and the cost for me was 6$. On the one hand, 6$ for three printed pages sounds a lot - those had better be good pages. On the other hand: they were scanned and saved as a .pdf, and while three pages don't take all that much time to scan, the amount of work which still happens manually in the process of scanning and registering is definitely worth 6$. The priceless part is that I can search for the article on the net, make a new account, pay for it, gain access where it's stored and download it in 10 minutes. I love the information age!
