I've managed to scrape SBR's own odds site for opening and closing lines for all MLB games back to 2007 (and will have it done for other sports soon), but I'm wondering if anyone knows of a place where I can get opening and closing odds prior to 2007. A scoreboard format of the webpage would be fantastic, but any data would be great since I don't think four seasons' worth of data is enough.
Four seasons of MLB data is a ton of games. That's plenty of data unless you're looking at some obscure subset. Furthermore, going back too far in time may actually begin to hurt your data as runs were scored differently in that era.
