Head, Digital Content & Collections


Kat Hagedorn is the Head of Digital Content & Collections. She is responsible for leading and managing the creation of over 290 digital collections of images, texts, and more from libraries and museums across the campus and the region. The department is deeply involved in all discussions regarding the suitable, long-term preservation and appropriate access to our content, at the digital object level and at the repository level. She is heavily involved in HathiTrust Digital Library, as the Michigan Digitization Project (MDP) Coordinator and as the HathiTrust Digital Object Quality Corrections (DOQC) Coordinator.

The department is also responsible for U-M's OAI metadata provider which includes descriptive metadata of HathiTrust public domain texts and the U-M Library's image and text collections. For 8 years, Kat maintained and grew the OAIster project, a search gateway for OAI harvested records leading to digital objects, initially Mellon-funded in 2001-2002. As part of a collaborative agreement with OCLC, OAIster was transferred to OCLC in October 2009.

She was Librarians' Forum chair from 2014-2015, and has served on the Forum as Secretary and Member-at-Large. She chaired the Usability Group from 2005-2007. In 2005, she was named a Library Journal Mover & Shaker. Her previous experience is in information architecture (with the Argus Associates firm) and ontology and taxonomy consulting (with the United Nations Food and Agriculture Organization in Rome).


Kat received her MLS from the University of Michigan School of Information in 1996.
