Updating documents from several years ago (the current one was originally written in 2018) pdflatex tells me I have old font commands such as \sc and \bf in the bibliography. I don't find them when looking in jabrefbib.bib; for example a 1982 book and a 1940 article.
I need a clue stick on where to look for these errors; an example from the LyX error log is: l.4 {\sc Aitchison, J.} 1982. You should note that since 1994 LaTeX2e provides a new font selection scheme called NFSS2 with several new, combinable font commands. KOMA-Script classes had defined the old font commands like `\sc' only for compatibility with old LaTeX 2.09 document styles of Script 2.0. Nevertheless, these commands are deprecated and undocumented at least since 2003. Since 2013 KOMA-Script classes warned about soon removement of these deprecated commands. Now, after two decades of LaTeX2e and NFSS2, these commands will not work any more. If loading a package results in this error message, you should contact the author of that package and ask him to replace the deprecated font command `\sc', e.g., by `\normalfont \scshape `. Otherwise you should reconfigure or replace the package. If you have used the old font command `\sc' yourself, you should replace it, e.g., by `\normalfont \scshape '. To make it work for now, you can use the already also deprecated class option `enabledeprecatedfontcommands'. The JabRef bibtex source for this article does not contain {\sc. Help's needed.
