The base theater and library were located to the east of the parking lot in the HSA East Compound.
I remember the library as being somewhat small, but with a decent selection of books. I know that I checked out Formosa Betrayed from there. Someone had scrawled on the inside of the front cover, "Is Lie!" I don't know if it was all true or not, but I think that much of it probably was.
For some reason, I don't remember going to see movies in the compound. But if it was like other military theaters of the period, admission was cheap and the movies were fairly current. The National Anthem would have preceded each feature -- while everyone stood at attention, of course --and smoking would have been permitted.
If anyone disagrees with any of these fading memories, feel free to straighten me out.
