The deputy director of the Arlington Heights Memorial Library has been named executive director of the Aurora Public Library and will begin her new duties in late September. Daisy Porter-Reynolds will replace Eva Luckinbill, who has served as executive director for the past 15 years. Luckinbill, who played a key role in securing the site for the new downtown library and is overseeing its construction, will remain with the library in a consulting role as director emeritus, officials said Thursday.
