The Swiss National Library has launched eBooks on Demand.
Here's an excerpt from the press release:
The Swiss National Library (NL) now offers a digitisation on request service for out of copy-right books. This new paid service is known as "eBooks on Demand" (EOD). The NL already lists more than 100,000 books available for digitisation, which can be provided as a PDF to customers. . . .
To date, more than 100,000 books (mainly older publications, since only they are not under copyright) are available on request in digitised form, and can be delivered to users as an e-mail attachment, or by post on a CD.
Such works are marked in the online catalogue Helveticat (www.nb.admin.ch/helveticat) with the EOD symbol, which serves as a link to the order form. Submitting a form triggers an invoice; once this is paid, the reader receives the eBook. On request, for a small supplement, a paperback may also be supplied.
"eBooks on Demand" is a project of the NL and over 20 other libraries in ten European countries (www.books2ebooks.eu).
