I'm working on implementing the MARC Format for Holdings Data (MFHD) standard for Evergreen as part of the serials module.
Unfortunately, my work is being hampered by a lack of "real world" examples of MFHD records. If your current ILS supports MFHD and you are willing to send me a file of MARC holdings data that I can use to test my code, please let me know. - David
