Adding/Showing Columns for PrimaryID or ISBN

LisaBarry · 12-08-2021, 11:02 AM

Hi,

I need to be able to check if the Identifier is filled out on a large number of EPUB files. I think Calibre looks like a tool that could possible provide me with this functionality. However, I cannot see this column by default and I'm wondering how I can show or add the column to see the information I need.

From looking in the .opf file code of my EPUBs - the Identifier number I need to check appears to be here:
<dc:identifier id="PrimaryID">360026123592</dc:identifier>
And here:
<dc:identifier id="ISBN">360026123592</dc:identifier>

If I could show either of these numbers in a column that would be great. I tried adding custom columns but I'm likely not doing it correctly (see screenshot).

I would greatly appreciate any help/suggestions on this.

Thanks,
Lisa

Rather than bloat the DB (or process) by adding a calculated column:

A search
identifiers:false will show books that Calibre ha NO identifier entries

Use the Tag Browser Expand Identifiers:
click once (green) to Show WITH, twice (Red) missing that type. Holding the control key allow building combinations
AND you can Save that search Click Saved Search at the far right:add

Those two columns you have should be shown in the book list.

Perhaps they are off the right edge, is there a horizontal scroll bar?

If you use the View Manager plugin you'll have to check them in its Columns in Default (Left) pane list.
