The 1st Academy Awards ceremony was held in 1929 with Janet Gaynor receiving the award for her roles in "7th Heaven", "Street Angel", and "". Currently, nominees are determined by single transferable vote within the actors branch of AMPAS; winners are selected by a plurality vote from the entire eligible voting members of the Academy. In the first three years of the awards, actresses were nominated as the best in their categories. At that time, all of their work during the qualifying period (as many as three films, in some cases) was listed after the award. However, during the 3rd ceremony held in 1930, only one of those films was cited in each winner's final award, even though each of the acting winners had two films following their names on the ballots.
