‘Labeling’ or ‘Labelling’?

“O, sir, I will not be so hard-hearted; I will give out divers schedules of my beauty. It shall be inventoried, and every particle and utensil labell'd to my will: as - item, two lips indifferent red; item, two grey eyes with lids to them; item, one neck, one chin, and so forth. Were you sent hither to praise me?”

As one might expect, it is a US vs. the rest of the English-speaking world issue, with the US preferring the single l in labeling and labeled, and everyone else preferring the doubled l. (The quote above is from Twelfth Night.)

Both are correct, but it is worth remembering when doing web-searches, for example.
