Are you ready to expand your MARC editing toolbox? This presentation will look at a variety of advanced MARC editing tools, libraries, and techniques to give you more options when wrangling your institution’s MARC data. Over the preconference, we will look at advance MarcEdit functions, like working with Regular expressions, automatic record harvesting and XML data conversions, as well as examine the new toolkit, MARCNext, designed to let catalogers explore adding linked data concepts within your MARC data. We’ll look at OpenRefine, and how uses can make use of OpenRefine and MarcEdit to perform powerful editing tasks that use to be hard to imagine without writing code. And speaking of coding – yes, there will be code. From MarcEdit’s Script Maker to tools you can find on Github, the speakers will endeavor to provide attendees with the information that they will need to address even the most difficult MARC editing project. This program is a reprise of last year’s successful and popular workshop.
