My understanding from research, education and training is this; What you refer to as a salt-print is what Talbot frequently referred to as a "photogenic drawing" (essentially a photogram on salted paper sensitized with silver nitrate) and I think this is where much confusion sets in. What I (and just about everyone I know) refer to as a salt-print (or salted paper print) is the later process Talbot used to make prints from his paper negatives (i.e., the calotype). While the basic printing process is similar, the formulae are a bit different.

(Slightly OT, albumen prints are just salt-prints on albumenized paper)
