With the eBooks on Demand service you can order the requested book as a digital edition.
And this is how the service works:
The requested book is retrieved from the library. In case digitisation is not possible, you will immediately be notified. Otherwise, the book is carefully scanned using special book scanners. Then – depending on your order and the condition of the book – free of charge automatic text recognition is carried out and the digital images are merged into a single file in PDF format. After online payment by credit card or ClickandBuy the eBook will be immediately available to you to download.
