Greetings fellow NR Members--
I wanted to share that I have been doing some research in Mexicali and found a great resource for historical documents at the Instituto de Investigaciones Históricas, Universidad Autónoma de Baja California in Tijuana.
They have a great collection of historical records for the entire state of Baja California, I found a military document pertaining to a family member who was taking over the command of a military post in Mexicali in 1905. The archives can be accessed by the general public, and they allow non-flash photography. They are also very helpful and currently, there is no cost to access or photograph a document.
