Texas Border Crossing Records

I am over at the National Archives looking up border crossing records and am having no luck finding El Paso crossings from 1916. Does anybody know if these crossings are available on microfilm anywhere? The college student staff member who is working here tonight told me that those years for El Paso are not filmed... but I want to make sure.

On a brighter note, Chris Pineda, I have found the border crossing records for your great-grandparents Nicanor Pineda and Emilia Gonzalez. I will scan them and send them to you.
