New Individual Ebooks for April 2021:
We have been scanning and adding the earliest GPS papers into our repository.
In the early years of Caltech, the GPS Division was known as the "Balch Graduate School of the Geological Sciences".
Many papers were written by well-known researchers such as John Buwalda, Beno Gutenberg, Charles Richter, Chester Stock, among many others.
To see these early papers, beginning from 1925, please visit the repository here. Please note, you will need to log in with your Access credentials to see the list.
We will continue to add more papers in the future.
