Nice to see my Book Fixture getting a workout at the UCLA Library Conservation Center, battling all 1,389 pages of Gasper Schott’s 1667 Physica Curiosa. Typical of alum tawed books from this time, the spine is now very inflexible; note that the leaves start to drape about 2cm from the folds. These books are a bear trap, err, make that an elephant trap in this case.
Thanks to Chela Metzger, Library Conservator at UCLA, for initial impetus for the fixture. And she is now Tweeting!
