Whilst I can accept collecting the EB, I'm wondering about reading the '98 edition, because it seems to me that I'd be trying to work out if the information was still current .....
And yes there are no doubt plenty of exceptions to the currency rule like the number of bones in the body of a human or animal etc but there are other things that could change and I wouldn't know it of my own volition (which is why I'm reading the EB in the first place).
So I'd then probably have to fact check what I'd read in the '98 edition with either the latest edition of EB or something else.
