There's an excellent resource in the Joseph Smith Papers for anyone who wants to compare different editions of the Book of Mormon, including the Original and Printer's Manuscripts.
The links to the Original Manuscript are not live yet because the physical book was published recently, but if you get the book you can find the references.
Eventually they will put the Original Manuscript material online so everyone can see it.
This is the type of resource that makes the Joseph Smith Papers so invaluable. Great work!
The next step, hopefully, will be translating this material so people who don't read English can appreciate it. That will be a long ways in the future.
