I have found this 264 _1 with 264 _4 coding to be a major time consumer when using RDA. For my local system, I must now copy what I put in 264 _4, e.g. ©2010 into 264 _1, delete the former, and then download. I fail to see what the repetition of what I put into these two MARC fields accomplishes for users, and it wastes time.
