Bulk delete "Ids" ?

I have downloaded a lot of Epubs books, and "cleaned-up" the metadata, but I can't bulk-delete the "IDs:" ones !



Is there a simple way to do that, or will I have to do it one by one ?

Thanks in advance for any tips...

The "Library Codes" plug-in can optionally easily delete any and all Identifiers except for: ISBN; ISSN; Z*; DOI; and Identifiers created specifically by the LC plug-in, such as for OCLC, ISNI, LCCN, LOC_LCCN, OCLC-OWI, LC_AUTHORITY_NAME, VIAF_AUTHOR_ID, etc.

So, it will optionally purge your books of Identifiers from Google, Amazon, etc.

Obviously, beauty is in the eye of the beholder. Some people find the Amazon ASIN Identifiers highly useful and even indispensable because of their Amazon software and hardware. Others, not so much. I personally do not, and use LC to delete all Identifiers other than those that it will never delete.

To delete "all" Identifiers, you could use the Bulk Edit Search and Replace function.

By the way, your example ISBN is the old ISBN-10 format. The LC plug-in will automatically convert them to the modern ISBN-13 format if you wish to keep them.

In bulk search and replace (select a few books, edit Meta, tab Search and Replace), I use this template to delete junk identifiers and just keep ISBN and Goodreads:

Code:
{isbn:|isbn:|, }{identifiers:select(goodreads)|goodreads:|}
See attachment.

Tip: You can omit the select template and keep the rest to delete every id...

I am actually wanting to build a templete to do the exact oppisite. Clear ISBN and Goodreads from identifiers. I am having trouble though, and could use some guidance. What I have used so far has either deleted everything or nothing at all.

The Job Spy plugin has 2 different 'metadata' tools for mass-maintenance of identifiers.

Thank you, but I was hoping this was possible using the built-in Search & Replace option. Using a template, I have tried several combinations but nothing is working for me.

Use the following search & replace. Run it twice, once for ISBN and once for goodreads.

It can be done in a single go by using a template by using list_difference to remove items from the identifiers list. I don't see the point in working this out if one isn't familiar with set arithmetic.

I did not think of PUTTING back just ISBN without a value
Once again, the developers have thought of almost every option.
