Another thing I found interesting is that dwarves and halflings don't get any bonuses to their saving throws vs magic or poison, while elves are immune to sleep and paralysis.
After playing D&D for years, some of these classical racial abilities (infravision, resistances) seem to be natural, and everything that's different seems strange. The only question is, did these have any roots in Appendix N? I didn't read everything from the appendix, but in those rare novels which are on the list and did include demihumans, I don't recall any, which included infravision, halflings being good with slings, dwarves resisting magic easier, elves resisting sleep and charm spells or an elf facing a ghoul.
