Hi,
Sorry to bother you.
There's a slight error in the citation style. This relates to non initial citations. The JEA guidelines http://journals.sagepub.com/pb-assets/cmscontent/EGA/JEA_Referencing_Style.pdf lay out citations thus:

Initial Citations Examples
J. L. Campbell and O. K. Pedersen, 'The varieties of capitalism and hybrid success', Comp. Polit. Stud. 40 (2007), 307–332.

I. Mares,'Firms and the welfare state: When, why, and how does social policy matter to employers?' In P. A. Hall and D. Soskice (eds.) The institutional Foundations of Comparative Advantage (New York, 2001), 184–213.

Subsequent Citations
Cambell and Peterson, Comp. Polit. Stud. 40, 307–332.

Mares, in Hall and Soskice (eds.) The institutional Foundations ,184–213.

Bibliography
None (officially)

The CSL style as it currently stands renders initial citations mostly correctly , however journal titles should use the short form and first names are always replaced with initals

In regards to subsequent citations, the CSL style (incorrectly ) cites in the following manner:

John L. Campbell, Ove K. Pedersen , 'The varieties of capitalism and hybrid success'

Mares 'Firms and the welfare state: When, why, and how does social policy matter to employers', 184-213.

Other things

When a specific edition of a book is cited the citation follows:

Initial Citations Example

A.H Gardiner, Egyptian Grammar: Being an Introduction to the Study of Hieroglyphs (3rd edn, Oxford, 1957), 1-6

Subsequent Citation

Gardiner, Egyptian Grammar 3 [ edn # in superscript], 1-6.


Thanks for any help you can provide.

Kind Regards
David

Thanks for working on this, I really appreciate it. You're definitely on the right track. However I did notice two small things.

In journal articles the CSL incorrectly authors names in full.

CSL Examples
1.Linda Evans and Alexandra Woods, ‘Further Evidence that Niankhkhnum and Khnumhotep were Twins’, The Journal of Egyptian Archaeology 102 (2016), 55–72.

2.Linda Evans and Alexandra Woods, JEA 102, 55–72.


In the first citation it should be
L. Evans and A. Woods, 'Further Evidence that Niankhkhnum and Khnumhotep were Twins’, JEA 102 (2016), 55-72

The Second Citation

Evans and Woods, JEA 102, 55-72

Reading through the JEA guidelines now it seems ibid. and id. are still occasionally used ( see the Guidelines 6-7) but use of Latin abbreviations is being "minimised. "


What are your thoughts on the issue of ibid and id? It seems the guidelines themselves are somewhat ambivalent on whether to use them or not.

Personally, I'd leave the Latin abbreviations out or possibly make an alternate version with them, but I trust this to your personal judgement.

Also would it be possible to get edition # for books to appear in citations as discussed in my previous post.

I can try and edit this using the visual editor ( I am very much a novice), if you're too busy, I really appreciate the hard word you've done so far, and thank you for any further assistance you might offer.

Thanks
David

PS: Here is a recent article following the JEA format, for reference https://www.academia.edu/30170294/Further_evidence_that_Niankhkhnum_and_Khnumhotep_were_twins_Journal_of_Egyptian_Archaeology_102_2016_55-72

specifically, it looks like you have the authors either in single-field mode or entirely in the last name field. You want them entered as Evans, Lina and Woods, Alexandra with last and first name in separate fields.
