Skim Editor's review

Finding a low-cost program that can edit or add notes to a PDF file can be hard. Finding one that can collate all of the changes as well seems almost impossible. However, Skim For Mac might be able to solve your dilemma, as it allows users to place marks and notes into PDF files and save all of those adjustments separately as well.
