Yes and no. For personal work, I have one catalog for every calendar year. For client work, I create a new catalog for each job/project. I like to use separate catalogs for everything to keep the work self-contained and easier to backup and archive. I also only have a MacBook Pro with a 512GB SSD. I only keep current active projects and personal work on the internal SSD. Everything else gets dumped to external drives.
My personal catalog for 2017 contains 1476 photos total. I only import final selections into Lightroom. The rest just gets archived on my backup drives (just in case). By only importing the keepers into Lightroom, I don’t have to worry about long preview rendering times for files I will never use, and I can keep my entire year’s worth of personal work on my internal drive.
I do have to juggle more catalogs, but there are some jobs that I never go back to unless I’m looking for portfolio material. No sense in keeping all of my work in a master catalog of most of the files are rarely touched.
