This series is the largest series in the collection, containing 3.5 linear feet of mostly bound research notes. These notes include charts and many graphs attached to pages with aging tape, making the notebooks difficult to use without special care. The notebooks in this collection are written in Anchel's handwriting or contain only a few pages of colleagues' notes. Her contributions may also be found in other notebooks from the lab. These other laboratory notebooks can be found in this series, both in other collections and shelved at the beginning of Record Group 5.
