If you do enter a Start Date, your search will be much faster if you also enter an end date. Except for Start Date and End Date, numeric fields and numeric words within text fields are not indexed. Selecting an Object Type of Coin will slow your search. In general, it is a very good idea to start with broad searches. Library Search Year of publication should be entered as a 4 digit number.
