Type collections: Use the menu at the bottom to select the year/range to view. Marks in the leftmost column ("X" or "SET" or "J", for example) identify cards I already have. I want one card from each set without these marks.
Player collections: select the player using the menu bar at the bottom. To move left and right in the player list, click the arrows at bottom-right. Or select this link for the spreadsheet in HTML form (for smartphone users). Cards with an X in the left column are ones I don't need.
Vintage Topps (through 1979): Cards listed in this spreadsheet are ones I currently have. Condition isn't too important.
Awards and Leaders: I need one single card for each player or team listed. If a player is listed multiple times, I need multiple cards for that player. If a team is listed with a player, I need a card with the player shown on that team. Here is a link to the HTML spreadsheet.
