Thanks! You are, of course, right! Thing is, I tried the macro using some actual titles, and some of them were not properly formatted. Taking a close look at them I noticed there were apostrophes or exclamation points in them. For some reason, the macro skips those titles, as in:

46. First Magazine’s Entry 1.8, April 1960
47. Second Magazine 36, April 1960
1144. First Book, September 1981
1145. Second Book, September 1981

Is there a way for the macro to ignore apostrophes, exclamation points, and so on, so that all titles get italics?

There are also some 300 titles that are not followed by a comma or a number, as in:

74. Mindscapes: Poems for the Real World
Richard Peck, ed. | Dell Publishing Company: New York, NY | 1972

After running the macro I get this:
74. Mindscapes: Poems for the Real World
Richard Peck, ed. | Dell Publishing Company: New York, NY | 1972


The title line is followed by the editor's name in the next line. Both lines are separated by a paragraph break. Could this be used in the macro somehow so that when there's no comma and no number after the title--but there's a paragraph break--then the italics are not used after the title?
