At my university, there was 3 day lending policy. With renewals within the day of return. Due to a limited selection, it was possible for others to put a 'hold' on it. This means library staff would keep it behind counter for up to a week before releasing it to the next hold request or put it back on shelf.
Since some undergrad books were in heavy demand (especially due to assignments/exams) when it's common to see holds. Some students have learnt to put the book somewhere else in the library so they could have exclusive privilege of reading it.
Conversely, I haven't heard of the professors or anyone hoarding lent books. All holds I have placed eventually turned up available in <3 days. Your two weeks policy is very generous and something I would have liked over 3 days which seems quick.
