Lost hardcover edition of 'To Kill a Mockingbird' with a personalized bookplate, misplaced at Springfield Public Library near the fiction section study area.

I misplaced my beloved hardcover edition of 'To Kill a Mockingbird' at the Springfield Public Library last week. I had it with me while reading in a study area near the fiction section, but when I went to leave, I realized I had left it behind. It has a personalized bookplate inside the front cover.
