For most people at DSL, the biggest benefit of all those unsmooshed fields we now have in our catalog is that subject and name headings can now be used properly. For me, the biggest benefit is that I can now run reports that will allow me to do some of our authority work in batches. The process still takes time, and there are so very many headings that will need to be dealt with individually, but being able to do any of this in batch makes me happy. Yesterday, I started writing up procedures for how the reports need to be run and massaged so that batch searching with them is possible, but I've already loaded 10,000 or so authority records with the help of this method, so I know it works.
By the way, prior to our unsmooshing project, those 10,000 authority records would have probably taken me more than 4 months to go through and load, assuming that the resulting shoulder pain from moving my hand back and forth between my mouse and keyboard for each record didn't completely cripple me. I ♥ batch searching.
