They never said it was going to be micro payment. But at Ingentaconnect, a database for selling academic articles, a five-page article costs 26.74$. That's more than 5$ a page. OK, so I might have to buy the whole volume if I was to buy the paper version, but then I would have all the other (quite interesting) articles as well, and not a leaflet worth its weight in - well, at least silver.
It looks like an interesting database though. A good search tool, if you know other ways of getting your thin, inkblotted scholar fingers on the content.
