The Authors Guild and the Authors Alliance both support the application of fair use when authors quote from pre-existing works when writing new works on the same or similar topics. But the Guild refuses to accept the different purpose fair use cases. The Authors Alliance has a more positive view of the different purpose fair use cases. If the Supreme Court decides to review the Google decision, the Authors Alliance will file a brief to explain why Google’s different purpose use is much fairer to authors than the Guild has so far been willing to admit.
