About the SABR Home Run Encyclopedia
Much of the data on Baseball-Reference.com's Home Run Logs comes
from the Tattersall/McConnell Home Run Log, a database of all homers
hit in the major leagues since 1876. This project was begun in the
1940's by John C. Tattersall and was continued after Tattersall's
death in 1981 by Bob McConnell, one of SABR's original 16 members.
David Vincent, another SABR member, has since assumed the leadership
of the project. Baseball-Reference.com has licensed this remarkable
database from the Society for American
Baseball Research. All credit for the data therein goes to the
intrepid researchers who digitized this data from archival sources.
For years from 1914 to 2014, RetroSheet play-by-play data has
been used whenever the home run occurred in a game for which we have
complete play-by-play data.
There are a handful of cases where the home run logs totals do not
agree with the totals on our player pages. We are working to
reconcile all of those differences, but believe that in all cases the
Home Run Encyclopedia is correct.
