Thanks for reply I truly appreciate the response. It seems that 'line' and 'total' variables are the most populated when going back in time (~2005 for NFL). Things such as "line mgm, line wyn, line mir, line pb, etc" are much more sporadically populated. I'm more specifically wondering which sportsbook (or multiple) is the "line" and "total" derived/scraped from. Wish you the best of luck in the upcoming season.
