I have personally verified (I have easy access to the public copyright  
records office) that the original copyrights to the "Interlingua - English  
Dictionary" and "Interlingua Grammar" (both editions) were never renewed  
in the USA, the country of original publication. I am not an intellectual  
property lawyer, but to the best of my understanding, that means that in  
the USA, at least (and I am guessing in other countries under the  
international copyright conventions), these two works have passed into the  
public domain, the original copyrights having expired. I don't know about  
anything else in the bundle.
