I like to do some historic work.

Multi-sport events change

I digged in old newspapers and was able to find a lot of reports and results of the Aquatics at the 1922 Women's Olympiad, 1930 Women's World Games and the 1934 Women's World Games; that couldn't be found anywhere else on the internet. Next to athletics, I also created pages of the other sports at the multi-sport events. See links to these pages in the templates below.

Women's Olympiad / Women's World Games (event pages)

I did research in old newspapers on the earliest (international) women's fencing competitions.

And also created many articles of female fencers in this era
