We have now added the Full Nominating and Voting Statistics historical data for the 1943 Retro Hugo Awards (awarded in 2018), 1946 Retro Hugo Awards (awarded in 1996), and 1954 Retro Hugo Awards (awarded in 2004).
We continue to update historical data for past Hugo Awards as data becomes available to us. If you have historical Hugo Award data (such as nominating and voting statistics) that are not shown on the page for that year’s Awards, please contact us so we can add it.
