Yes
Clevnet consortia as bought Overdrive (
http://www.overdrive.com) solution for libraries.
It was, the first public library to have a complete solution to manage commercial eBooks in a library environment concerning the circulation part of the library activity - and this was in 2003!
The solution puts a “Mission Impossible” type of auto diactivativation setting in the file downloaded, making it stopping opening after a period of time - normally 14 ou 21 days for eBooks - in this solution this is configured by the library itself.
For this to work one must have a reader with the capacity do read in the format the library has (mobipocket in this example), but the reader it must also have a working internal clock, one that counts minutes, hours and days, and who knows actual date correctly.
What I’m inferring is that the Cybook as not the date set by default and until Bookeen puts on the OS a option of us doing it from a menu, they have come out with the procedure described above, the one that for now sets the date correct (and possibly puts the clock in motion).
As I said, this solution is one of the DRM options available in several formats (lit and PDF have this option too), and make part of the solution provided by Overdrive for the circulation problem in libraries - this way a library does not have to concern itself with users checking in their books, at 00:01 minute of the 15th day (or 22th), the file stops working and the counter of the eBooks available for that title in the library is incremented by one (if it were 2, 1 cheked out and 1 available, there are now 2 available).
For a bought eBook there is not that restriction, that’s why ProfJulie does not see that “counting down” information in his bought eBook.
