Some interesting ideas on how libraries could be changed by retail technology can be found here. This is already commonly used by retailers.
In a Brent context, one can see it being used to best advantage in a co-located library such as Wembley or Willesden. For instance instead of queuing at the One Stop Shop above Wembley Library, people might wait in the Library and be alerted when their appointment came about upstairs. It also shows that the trope one so often finds in newspaper articles of relying on childhood memories of how libraries used to work is inadequate. Like any other living services public libraries are (and have to) develop as technology and society changes.
