% These sourcemap declarations allow for .bib file oddities. Additionally, to comport with MLA expectations, they modify strings in publisher fields, drop unneeded parts of URLs, and look for patterns in a URL field to fill in missing eprint fields. If the choices here seem to do too much, use "style=mla-strict", which makes fewer accommodations and more exactly prints entries as they're defined in a given bibtex file.
