This article presents an interview with Casper Grathwohl, VP and publisher of reference at Oxford University Press (OUP), regarding his background of reference publishing, his role in OUP, and his plans of moving on with Oxford Bibliographies Online (OBO). Over the past 12 years, Grathwohl, has led a successful transition of the venerable publisher from print reference to online, creating one of the leading digital publishing programs in the world. Oxford Art Online, Oxford Languages Dictionaries Online, and Oxford Islamic Studies Online are just a few of the resources that have set a high standard for the way research happens--propelling OUP to the forefront of the digital revolution and affording it an enviable place in the minds of librarians.
