Kerstin Wendt has been working for about 30 years in the Hamburg State and University Library – and almost the whole time as a member of the IT-Department. As a “system librarian” she had to introduce und customize different software tools in the library. Moreover she tried to explain the library needs to IT companies and software developers. Since 2006 she is involved in several digitization projects. In 2011 the library decided to proceed in the field of digitization with the open source tool Kitodo – according to the general preference for open source software in the Hamburg State and University Library. Their commitment covered from the beginning participation in community activities: Kerstin is a member of the kitodo community board at present and she takes part in a third-party funded project to renew the complete codebase of the workflow tool Kitodo Production.
