Why so few 15C/11C application and program books?

The EduCALC index shows a small handful of items:

"An Easy Course in Programming the HP-11C and HP-15C" by Wadman and Coffin (catalogs 23 thru 52)
"ENTER" (translated from the French) by Jean-Daniel Dodin (catalogs 23 thru 59)
"Substantial Programs for the HP-11C and 15C" by Thomas Beers (catalogs 35 thtru 47)

That last one certainly has me intrigued. I wonder if there are surviving copies out there somewhere.
