Looking for collection of short stories

I'm looking for a collection of Batman short stories I had read when I was younger. (Early to mid 90s).

These were short stories, not comics and not illustrated. I have a recollection they were appended to a paperback novelization of Mask of the Phantasm, but I'm not certain of that after all this time.

None of the books I can find listings for describe content other than Mask of Phantasm, but I'm certain the book was far thicker than to only include the short stories.

I'm afraid I don't have any concrete enough details of any of the stories to narrow it down further.

Thank you.
