"I want to be able to cite 3 articles in the text with commas between the first two and "and" between the 2nd and last. As for example (Smith et al, 2002, Jones, 1999 and Bloggs, 1986). How can I do this?"
Firstly, you need to set up the multiple citation separators
to use commas; by default this usually uses semi-colons.
Multiple citation separator control is at the bottom of the
Citations Template area. Insert a comma, and remember to add a space
afterwards.
To add the “and” before the last cited item is more
difficult. There is a way to do this but it has to been to done to each
citation when they have been created in Word. It cannot be done through the
output style on EndNote.
In Word make sure the cursor is in the required citation.
From the toolbar choose Edit citations (or right click with
the mouse).
An edit box will appear with all three citations displayed.
Click on the last citation and then click in the prefix box.
Type 'and' then a space.
Click on OK. This will allow the word to appear before the
last citation. Unfortunately the comma appears as well, but at least this does
allow the and to be added manually, as desired.
