Preparation of this online version of Português para principiantes was supported, in part, by an Educational Innovation (EI) Small Grant provided by the University of Wisconsin-Madison. The authors wish to extend their appreciation to Steel Wagstaff, of Letters & Science Learning Support Services (LSS), for his invaluable assistance in the completion of this edition. We would also like to thank Mariana Oliveira and Michael Alves Pantaleão for their general help on this project and, in particular, for providing recordings of the dialogues and vocabulary.
