One of the best online resources for writing is Purdue University’s Online Writing Lab (OWL). The grammar section of the OWL covers a number of common issues, including common spelling errors,the difference between adjectives and adverbs, and the proper use of numbers. As historians, we deal with dates quite a bit. So, one important thing to remember is that any number that starts a sentence should be spelled out. For example, it is fine to say “Thomas Jefferson was born in 1743,” but not “1743 was a momentous year, because of Thomas Jefferson’s birth.” Rather, “Seventeen forty-three was a momentous year…” is the correct form.
