**Quantum Gravity Problem:** **Below is a compilation of George Karatheodoris’ scanned notebooks. His death resulted in the bulk of his work on gauge gravity to remain unpublished. They are presented here in reverse chronological order. Volumes for previous years are still in the process of being uploaded. A complete volume list (indicating topics covered in each notebook) is found here**

##### **Why Scan the Notebooks?**

A note from the author explains: * “…I have to write extremely terse papers in the code (TeX code) for the articles. I will cite pages from notebooks in which details are carried out. I just don’t have time to make the papers pedagogical as much as I might like to.” *** **(from: **On an Algebraic Approach to Gauge Gravity**, February 2012-July 2012, p. 20.)

**Organization and Presentation**

The notebooks are scanned in their entirety as it’s impossible to know which the author intended to scan and reference for his articles. Each title block below begins with a the date, some topics covered, followed by the notebook’s “Page Link” below it. The “Page Link” takes the reader to the corresponding notebook’s webpage containing its PDF. The webpage also has author commentary transcribed from the notebook with corresponding PDF page numbers.
