Detroit Public Library years During his time at the Detroit Public Library, Croneberger wrote of three experiments the library was conducting in the realm of information services. One represented a traditional approach where librarians at the main branch of the library system contacted local organizations and maintained pertinent information in a card file. For the second one, the library collaborated with the city government. Calling it a "little city hall", the library would offer some of the services provided by city government on a neighborhood level. The third experiment centered on a concept known as a community knowledge center. The idea relied on the collaboration of the library community agencies with graduate sociology students. Students would study the community and provide the library with their findings. The experiments laid the foundation for the creation of the Information Place, the library's information and referral service that still exists today. Croneberger's work led to him being considered one of the founders of the information and referral movement. He went on to become chairman of the Information and Referral Taskforce of the National Commission on
Library and Information Science.
The Memphis years Croneberger arrived at Memphis and Shelby County Library system in 1975, a year before the city passed an ordinance that banned destroying or damaging library books. In 1980, he was the director when the first person was arrested for violating the ordinance. Lily Prymus was arrested in October 1980 after she did not show up in court in response to a summons. She was charged with not returning 13 books.
The Carnegie Library of Pittsburgh years In 1986, Croneberger began his 11-year stint as the eighth director of the
Carnegie Library of Pittsburgh. He brought his passion for the community and information and referral services with him by forming a partnership with the United Way of Allegheny County. Another partnership was formed with the Pittsburgh Mediation Center, which focused on conflict resolution. Public housing projects also became the recipients of library services under his lead. On June 11, the three-judge panel deemed the act unconstitutional, citing Croneberger's testimony three times in its decision. ==References==
