You would want to do this in the Query designer if you are new to SQL.
Open the query designer and select two tables, the Books table, and the selection junction table. The relationship between the tables should be visible between the two tables.
On the text menu, select View > Totals.
Select the Book Name field in the books table, then select the ID field in the junction table. Change the Total for this field to Count.
Select the relationship between the two tables, and check the check box that says "Show all records in the book table, and only those records in the junction table..."
When you run this query, it will show all the books, and then give you a count for all the times the book was selected. If the book was never selected, the field will be Null, and not have a 0 in it.
I know there is a way to add the 0, but I am not in front of Access right now.
Did that help?
