I am writing a college paper analyzing Paul's Epistle to the Romans and can't find a lot of information on how people reacted to his letter.
Do you mean the church in Rome? There is no direct evidence for this. The best I suppose one could do would be to analyse 1 Clement which appears to be from an elder in Rome to the church in Corinth, and would provide some very indirect evidence on the church of Rome, but even this is dated to late 1st century/early 2nd century and I would consider reconstructing "Roman reception of Paul's letter to the Romans based on 1 Clement" to be a very speculative study.
