I assume that I am not the first person to make this suggestion, but it would be very helpful if a user could select a set of images and then export the metada for those images (or selected metadata fields) to a list in Excel. This would greatly simplify the process of completing the list that must be submitted to the copyright office when registering photos for copyright.
I was actually surprised to find that this is not a feature in Lightroom. In my day job, I work with a cloud-based content management system in which we store Word docs, PDFs and Excel files. And in addition to being able to edit, download, copy and paste, etc. we can generate a list of records in a list view, which will contain only the fields of metadata that we choose and then export that list into Excel.
