Libraries Built by Users – An Interview with Annette Klein http://t.co/J2pHyiw0...
[...] the library can use an acquisition profile to select relevant eBooks from the total collection of titles available. Library users are given access to the desired titles on the aggregation platform, and the title data are entered into the library’s online catalogue.
When a user comes across a PDA eBook in the catalogue, it will look just like any other eBook in the library’s collection. Via a link contained in the title data, the user is rerouted to the provider’s platform, where a free preview of the book is initially available prior to purchase.
Full access, which requires payment, is only triggered by more intensive use – just what constitutes intensive use is defined differently from one platform to another: it may be if the same title is accessed several times, if it is accessed beyond a certain time limit or if the book is copied, printed or downloaded."
[...] The library can determine whether a book should be purchased permanently upon initial intensive use, or whether access should first be granted in the form of a temporary personal loan."
