It is so well contained – shows all the information that is important, and none that isn’t.
There’s a short header with logo, timestamp and my member id.
Then, right up front in the first box, it shows the book that I just borrowed, when it’s due for return, and any associated fees.
In the next box it lists the books I already have out on loan, with due dates for each1.
In the final box it shows any fees that I have outstanding. In this case it is £1.50 for two books that I had reserved (75p each).
Then there’s a concise footer reminding members that books may also be renewed/reserved online2 (how I do it), and over telephone (for digitally disinclined).
That’s all. Simple and sufficient.
