I am glad to see that Martin Francis has finally noticed that there is a new library at Willesden Green despite his determined campaign against it. It is a shame, but perhaps predictable, that his attitude should continue to be negative and critical.
However, it is a fair point that longer opening hours would be a major benefit, and would not necessarily be expensive. The room hire should be able to offset some of the cost, and it may be possible to charge higher rates at peak times such as Friday and Saturday evenings. It would also benefit library usage, even if it was only a form of limited availability such as the unstaffed hours at Wembley Library on weekday mornings.
