1. Go to Baseball-Reference.com

2. Look up the players you have in mind for this league. Note their ID codes, usually the first five or six letters of their last names and the first two letters of their first name plus a number, depending on whether they're in the minor league database or not. Most historical players will have played in the minors prior to their major league debut, so they may be in a minor league database as well, with more characters available for their player code, or if they were foreign or Negro League players who never made the majors, for example. Independent league players may also have ID codes for BB-Ref as well. Be aware, however, that some players may have the same first name, or at least share the first two letters of their first names as Baseball-Reference lists them in their player lists, so that is where the numerical part of the ID code comes into play.

3. Once you have collected all the codes of the players that you wish to use, then put them in a text file, like a Notepad text file, for instance, and include the season that you want to use for said players like so:

musiast01,1942,STL
ruthba01,1927,NYY

If you want them to go to specific teams once imported, use the desired abbreviations for the relevant teams. If not, do not include said abbreviations, and they will either go to the appropriate free agent pool or to the next appropriate draft pool, if you have the necessary box checked for drafting purposes. Do NOT forget to save the text file you are working on, as often as needed.

4. Then use the "Import Historical Players" function, and do as you like and as the pop-up then requests of you. You can import the player list where it says you should choose the text file to use, et cetera, as you like and can.

Hope all this information is easy enough for you to understand, and all. Please let us know if this helps you enough.
