I tried this and both annotations appear, but both source 1 and 2's annotations 'collide' on the same pages in the merged PDF since the annotations retain the same page numbers they had when they were created in source (i.e. let's say that source 2 has highlighted text on its page 1---on the merged PDF, the highlights for this text appear on its page 1 but the text isn't in the highlights since it appears after the last page of source 1 on the merged PDF).
So I think that the solution is this: can I directly modify the Skim Note files to change the page numbers for each annotation to my liking? When I open it in a text editor, I mostly see gibberish but there are certain intelligible characters such text from my
annotation and what appear to be pixel coordinates---I couldn't find page numbers though...

Subject: Re: [Skim-app-users] Preserve annotations after merging two annotated PDFs?
Before merging, export the skim notes for the two files to separate files (File > Export…). After merging, read them in (File > Read Notes…), make sure you uncheck "Replace existing notes" the second time).

Hi everyone (developers too?),
I have two Skim-annotated PDFs (sources 1 and 2) which I want to merge into one PDF in that order (I use CombinePDFs to do the merging since Skim cannot do this for me). Problem is, when I do this, the annotations for both source PDFs are gone in the merged PDF.
Q: Is there a way to *keep* the annotations after merging?
is no elegant solution, here's a kludge that I hope to carry to completion:
I have made some progress in that I *can* extract my annotations when I export as "Skim Notes" and save them onto the merged PDF by using "File > Read Notes...", but the page numbers for my annotations in the merged PDF are the same as they were in source---so that source 2 annotations are not in the correct location in the merged PDF. What I want to do is "shift" ALL the page numbers of source 2's annotations by an integer of my choosing (i.e. so that they correctly correspond to the "new" page numbers where source 2 resides in the merged PDF)
Please let me know if you have any ideas to make this work---this
would be great as I often find myself OCR scanning books one chapter at a time just so I can annotate them in Skim!
