Google along with a group of publishers and authors has proposed changes to the settlement of legal challenges to Google's mammoth book archiving project. The changes, among other things, limit the international application of the settlement. The changes did not win over some of the leading critics of the earlier agreement. Within higher education, opinion has been split, with some colleges in favor and other academic groups expressing concerns. Charles Lowery, executive director of the Association of Research Libraries, one of the academic organizations that has expressed concern about the previous version of the settlement, said via e-mail that the group was still studying the changes and couldn't yet take a position on them.
