Stephanie Browns detective comic trades

I'm reading more into stephanie brown. I want to read her in her first appearence (647) but the trades of detective comics it goes from issues 598 - 600 and then the next trade is 743 - 750.

Where did the 143 go?

If someone can direct me to a page of stephanie brown / spoiler trades it would be very appreciated.
