Analysis of information sources in references of the Wikipedia article "USL W-League (1995–2015)" in English language version.
From its formation in 1995 until the start of the Women's United Soccer Association — the first U.S. professional league — in 2001, the USL W-League was the top flight of soccer in the United States. It returned to that status upon the folding of the WUSA following the 2003 season, and remained the top flight — all as a semi-professional league — until Women's Professional Soccer began in 2009.
