I have to adapt the bibliography layout to comply with the IRC template:
References should be done using JRR house-style format: For journals - Authors’ names in caps, year in bracket, title, name of journal in italic, volume and issue number in bold, page number.
However, I cannot find this as biblatex package. The phys style comes close, but needs some editing. I have copied and renamed the phys.bbx and -.cbx files from the biblatex-phys.zip-file, placed them in my document home directory and have them running.
However, I cannot find the basic macro definitions to use them as a template for the changes. They should be in the biblatex.def file, but I cannot locate this. In a previous question this was answered for a Linux environment, but grep and kpsewich are not available in windows. Also, I cannot find the path /texmf/tex/latex/biblatex/ that was suggested as answer in another question. Neither the windows file search option or ultrafinder are of much help.

bstfile to use? Journals often use the old BibTeX way. – Johannes_B Jun 03 '18 at 13:44
