I wonder if there is an English translation of Fraïssé's paper "Sur l’extension aux relations de quelques propriet es desordres", appeared in Annales Scientifiques de l'Ecole Normale Superieure. Troisieme Śerie 71 (1954), 363–388." If not, where can I find the french paper (pdf)?
Also I'd like to know which text on model theory discuss details on Fraïssé theory, with one main result being a countable homogeneous structure is completely determined by its age. (The age of a countable structure is the collection of all its finitely generated substructures.)
