In short

Sports checklist names in Qosmo come from the open-licensed source lists below, baseball only. They are shown as each source gives them. Qosmo has not checked them, they carry no prices, and they do not cover every set or every year.

What Qosmo changed

Qosmo normalised whitespace, grouped rows into sets, and left out rows the source data contradicts.
