Certain EndNote fields contain special restrictions on what sort of data can be imported. These settings cannot be modified and apply to all import filters.
Author Fields
The words "And Others" get converted to "et al" and the word "and" is omitted. Years as well as parenthetical or bracketed text are removed by default. See Author Parsing.
Year
Only 4-digit numbers (1### or 20##) are imported.
Title
The following punctuation is removed from the end of a title:
Period, comma, semicolon, colon, forward slash, back slash, opening parenthesis, dash, and caret.
Pages
A "P" or "p" before the number is automatically removed.
Volume
A "V" or "v" before the number is automatically removed, as is a number that appears to be a year.
Issue
An "N", "No" or "No." before the number is automatically removed (this is not case sensitive).
