There is no full osteology of _Daspletosaurus_.  Yet.  Best work on it so
far is the original:
Russell, D. A. 1970. Tyrannosaurs from the Late Cretaceous of western
Canada. Natl. Mus. Nat. Sci. Publ. Palaeontol. 1: 1-34.

For _Albertosaurus sarcophagus_ there is only some really old literatue.
Currently.  Check out:
Cope, E. D. 1892. On the skull of the dinosaurian _Laelaps incrassatus_
Cope. Proc. Am. Phil. Soc. 30: 241.
Parks, W. A. 1928. _Albertosaurus arctunguis_, a new species of theropodous
dinosaur from the Edmonton Formation of Alberta. Univ. Toronto Stud. (Geol.
Ser.) 25: 3-42.

For _Gorgosaurus libratus_ there is a pretty decent osteology, again fairly
old.  More to come really soon!  See:
Lambe, L. B. 1917. The Cretaceous theropodous dinosaur _Gorgosaurus_. Mem.
Geol. Surv. Can. 100: 1-84.

Please note, though: osteologies (or at least cranial ones) of all major
tyrannosaurids are in the pipeline (ms in writing, in review, or in press).
Stay tuned!
