The only ones with access are those publishers who choose to subscribe, plus a few larger agencies (who generally limit their subscription to the genre they serve.) According to reports I've read, a single genre list costs about $25,000 per year. The full list is something like three quarters of a mill.
Now, RWA does provide access to the Top 100 Romance weekly list as a benefit of membership (with a $50/year subscription fee.) But that's the only organization I know that has any sort of access and it doesn't follow particular books from week to week. It's just the top 100, no matter which books they are.
Sorry.
