Using wildcards to italicize magazine/book titles

[cirerita]

Hello,
I have a loooong list of book/magazine titles--well over three or four thousand titles-- and I would need to find a way to italicize those titles.

The listing is something like this:

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

I'm a complete beginner re. the use of wildcards. If I use the following wildcard, I'm able to get to the first letter of the book/magazine title, but I don't know how to select the full title, not just the first letter:

[0-9]. [a-zA-Z]



Titles are always preceded by a number, which is followed by a period, and then comes the magazine/book title, always followed by a comma or a number.

The only variable which is unknown here is the length of the title. Is there any wildcard that would allow me to select the full title given there's always a comma or a number after the title?

There's a lot of additional info in each entry, so I can't export this to Excel, where it should be fairly easy to do.

Thanks!!
