This LibGuide attempts to document the features of MarcEdit, which was developed by Terry Reese. It is open source software designed to facilitate the harvesting, editing, and creation of MARC records. This LibGuide was adapted from a standalone document, and while the structure of the original document has been preserved in this LibGuide, it is also available in PDF form at the link below. The original documentation and this LibGuide were written with the idea that it would be consulted on an as-needed basis. As a result, the beginning steps of many processes may be repeated within the same page or across the LibGuide as a whole so that users would be able to understand the entire process of implementing a function within MarcEdit without having to consult other guides to know where to begin. There are also screenshots that are repeated throughout, which may provide a faster reference for users to understand what steps they may already be familiar with.
