When you first click on the AAT subject term box on the data entry form, you will see a message saying "No results found". Ignore this and start typing a word in the box. You will see a message which says "searching". Keep typing until you have entered enough letters of the word that you are looking for. A scrollable list of terms will appear. Click on the term that you would like to add to your record. To add a second term, simply start typing again.
