Hi all--

 

Here's the main page for the Archivo:

 

 

I found under "instrumentos de consulta" some search  pages. 

 

 

If you click Argenta III, then Argento II, you can then enter a search name/word, and you can select under the pull-down menu Groupo Documental "999 Todos los groupos documentos," which is the last choice.  Then  you can search all of the categories.

 

It appears they offer services as well, but I just located this site, so I'm still poking around.
