You might want to have lists of references, in the back, but with multiple such lists. Make an <appendix> to hold them, give it some structure (for an <article>, a leading <subsection>, such as the one you are reading right now), then follow with multiple <references> divisions. A typical citation will then look like: [J.3.2].
