Pooleys is frequently incorrect but I suspect it is not entirley their fault. No doubt they rely upon infirmation from the airfields themselves and I wouldn't be surprised if many simply couldn't be bothered to update their own info.

It is not the responsibility of airfields to keep third party documentation up to date. Their only responsibility is to the UK AIP, the third parties get their information from that although I guess some airfields do try and help. I have in the past, contacted some BIG third party documentation suppliers pointing out the error of their ways, and sent NOTAMs correcting their info.
If Joe Blogg Publications Inc comes along and decides to publish a guide then airfields cannot be held responsible for the information it contains.
