Currently there are about 620 books. If I want to add another book, I have to put the ID of the books in numerical order. Then manually give the next book the next number. I call it the ID because that is what the title of the column is.
In auto fill ID, (the record number ?) when you add a book, and you put the cursor in the ID column, it automatically gives you the next number, even if all the books are in alphabetical order.
We would do two sorts of searches, either all the books in a particular category, or search for a particular title or author. Nothing ever so complex. Your second paragraph is difficult for me to understand.
