How long does it takes rom request to delivery of an item?

NILDE processes about 220.000 ILL requests/year. Since its beginning, it has processed 2 Millions ILL transactions.

Each library constantly monitor their average turn-around time. This is calculated by NILDE as difference between the fulfillment (or un-fulfillment) date and the request date for each item, both on the borrowing and on the lending side.
In order to comply with the Rules and Regulation, libraries should keep their lending turn-around time indicator less than, or equal to, 2 (i.e., they answer requests in 2 days in average). We can see they behave much better than this.
Thanks to the virtuous processes, the whole community has improved these indicators:  the retrieval of a document within the network has become easier (fulfillment rate is 87%) and the global average time from request to delivery of an article has steadily decreased to 0.6 days.
