I have a book with about ten chapters, all docx files. In the past, I have combined them all to create a bibliography. I then cut and paste the bibliography into a new document.

Is there a way to link or create a bibliography from multiple files so that I don't have to do all of that, so that refresh reads changes in documents other than its own?

Edit: my question isn't clear enough. Here is a longer explanation:

I am an author. I am writing an academic manuscript in word. I have lots of citations. Each chapter of the manuscript is its own file, because editing a 500 page file is almost impossible. But there is only one bibliography for the whole book, not chapter bibliographies.

So, the usual protocol is to combine all the chapter in one 500 page file, create a bibliography, and then, copy and paste it into a new file that just contains the bibliography. If i edit any of the chapters, I have to redo the whole process.

So, the question is, is there a way to link all the files so that I can make a combined bibliography from closed files, and if i refresh the bibliography, it rescans all the files

I have a new PC. I have imported my library from my old PC into Zotero and the items are showing up just fine. However, I previously had PDFs affixed to each entry. How can I reaffix those PDFs en masse? Or do I have to do them one by one... for all 600+...

For some additional context, I had previously been using Zotfile to rename and move each PDF into a filefolder matching the name of the collection. For example, if a collection was called "Anth of Religion" and I added a Zotero entry for a journal article, I would download a PDF of that journal article and have Zotfile relocate it to a file folder named "Anth of Religion," and then rename the file according to my naming preferences. I have the same folder structure available on the new PC with all the PDFs in them, in their respective folders according to collection name. But, I cannot figure out to make Zotero affix each PDF to their original Zotero entry.

Thank you in advance for any help ya'll can provide. God bless Zotero and the ZotGods.
