The main shortcoming is that the 5th Edition stops at 2007.
The second is that the effect of updating is to reject what were formerly 'must-sees' to make room for the latest additions. So, I have no intention of participating in such wilful U-turns and will retain all those that subsequent editions have thrown out.
I nevertheless intended to source a copy of a later edition so I can come up to date, but since this is an annual exercise, I'll never catch-up.
Besides, the internet has made this job much easier.
