Importing PDFs with metadata

I am wondering about importing a set of PDF magazine issues into my Calibre library.

If I import tham via "Add Books" I get poor results because currently the only metadata in the PDFs is the magazine name, and I get a bunch of hard to distinguish magazines with identical names. I need the year and issue number to be imported as well, which matches how the magazines are published.

I can script exiftool (not the first tool I'd have thought of) to write metadata into each PDF.

But what does Calibre read from a PDF and put into things like dates and number-in-series?

You dont need to use exiftool, use the ebook-meta tool from calibre that will allow you to set all metadata in PDF including series. And that metadata will be read when adding the pdfs to calibre

If the file names are meaningful and follow a pattern, Calibre can also read the data using these.

It didn't work out for me, maybe because I didn't use a pattern that Calibre was expecting.

But the ebook-meta tool is exactly what I needed, especially because I want the metadata to live inside the original file whenever possible.

You can define the pattern yourself, but I think the file name is only useful if the name is already reasonably meaningful.

If there are too many changes, the tool makes more sense

You can write the metadata to the file anytime via Calibre
