Preface The cases in which a book that has already appeared in print is
reprinted by someone else are so varied, and occur under such different
circumstances, that it is equally impossible to condemn all reprints as it
is to defend them all. A precise definition and thorough knowledge of the
matter are therefore necessary if one wants to make a well founded judgement
on the lawfulness or unlawfulness of reprinting.
Not everyone knows the circumstances which are relevant here as
thoroughly as would be necessary; nor does everyone have the time and
inclination to devote so much consideration to one single question. So it
is not surprising that since everyone looks at it from a different point
of view, opinions on this matter have differed so greatly.
