PMCID as a new field for any entry


I need to reference PMCID in all NIH proposals and bio-sketches. Right now, i don’t see any way to do that. Please note that PMID is different and does exist and is accessible through Options>Customize Entry Types. Can you please add PMCID, - or better still - permit the user to add a new type not already listed in the dropdown box.


Hello @nataraj , this is already possible :slight_smile:

Go to options>customize entry types, then

This is what you are asking for, right?

Hi ThiloteE, thanks for the response. But I don’t want a new entry type (meaning a new article/book/etc.). What I need is to be able to add a new field to @article (for example). So, the bib file, after adding the new field would need to look like this for example. Note the new field pmcid = {}.


author = {Tonna, Joseph E. and Selzman, Craig H. and Girotra, Saket and Presson, Angela P. and Thiagarajan, Ravi R. and Becker, Lance B. and Zhang, Chong and Rycus, Peter and Keenan, Heather T.},
journal = {JACC. Cardiovascular interventions},
title = {Resuscitation Using ECPR During In-Hospital Cardiac Arrest (RESCUE-IHCA) Mortality Prediction Score and External Validation.},
year = {2022},
month = {Feb},
pages = {237-247},
pmcid = {PMC8837656},
volume = {15},
article-doi = {10.1016/j.jcin.2021.09.032},
issue = {3},
keywords = {extracorporeal cardiopulmonary resuscitation, extracorporeal membrane oxygenation},
language = {eng},
linking-issn = {1936-8798},
location-id = {10.1016/j.jcin.2021.09.032 [doi]},
manuscript-id = {NIHMS1745844},
nlm-unique-id = {101467004},
owner = {NLM},
print-issn = {1936-8798},
publication-status = {ppublish},

source = {JACC Cardiovasc Interv. 2022 Feb 14;15(3):237-247. doi: 10.1016/j.jcin.2021.09.032. Epub 2022 Jan 12.},
title-abbreviation = {JACC Cardiovasc Interv},

Sorry I had a misleading subject title; just edited it! Thanks.

But that doesn’t work. The ‘+’ works only if it is a field that is already defined and is in the dropdown box. If would be great if you let me know if it works for you in which case I will reinstall Jabref and try.

It works on

JabRef 5.6–2022-01-30–8ca6b7f
Windows 10 10.0 amd64
Java 16.0.2
JavaFX 17.0.2-ea+3

Could be that you have to restart Jabref before the changes in the preferences (options > customize entry types) takes effect.

The combo-box is editable, you can freely add any text there for custom, non existing fields

@nataraj Did it work for you? If yes, i will mark this topic solved.
