Lucy Sussex sent me this quote from a history of Macmillan:
'The moral seems to be that to be a good publisher you must take children and artists seriously, and that is a hard moral, for how does it differ from saying that to be a good publisher you must be a good man?'
Now that's kind of challenging. As a caveat, quite Buddhist in its demands.
