Nigel Whitfield on eBooks that ‘wear out’:

[New] Harper Collins eBooks sold to libraries will have a licence (enforced by the Digital Rights system embedded in the files) that allows a book to be loaned only twenty-six times, before it expires.

After that, if the library wants to carry on lending the book, it will have to buy a new copy.

I think—especially in harsh economic times—the publishers would do well to support anything that helps people to carry on reading, and learn to love books, rather than to put obstacles in the way, and make it more expensive for readers and libraries alike.
