Check both "source abbrev" and "source" in Web of Science to get correctly abbreviated journal names. ("Abstract" is optional). Note, this program is picky about newlines and white spaces; these should be exactly as they were provided by Web of Science. Try a copy/paste of the example above first and see whether that works.

Before you complain that it doesn't work, check that it really looks like the example above: two uppercase letters, one space, and then the text. No colons and dashes.
