My iPhoto library is brimming with images taken over many years; it's also in organizational disarray. That's why for the upcoming holidays, I'm going to create a new iPhoto library to store all of my holiday pics.
Starting fresh with a new iPhoto library
One of iPhoto's many features is the ability to work with multiple image libraries. By segregating images into multiple libraries, you may find that iPhoto is more responsive. And when you're searching for a specific image or type of image, you won't get distracted by unrelated images.
If you would like a hand at setting up one or more additional iPhoto libraries of your own, take a look at this step-by-step guide to creating and using iPhoto libraries.
