iPhoto Library Manager allows you to organize your photos among multiple iPhoto libraries, rather than having to store all of your photos in one giant library. You can browse the photos in all your libraries directly from iPhoto Library Manager, without having to open each library in iPhoto just to see its photos, and search across all your libraries to help track down a particular photo.
iPLM also gives you the ability to copy your photos from one library to another, while keeping track of photo metadata that is normally lost when exporting from one library and importing into another. Titles, dates, descriptions, keywords, ratings, faces, and place information are all transferred along with the photos, ensuring that you keep all that information you spent hours entering into iPhoto. Event and albums are also reconstructed when copied, and both the edited and original copies of each photo are copied as well. You can split up a large library into multiple smaller libraries, merge entire libraries together into a big one, or rebuild a corrupt library that is causing iPhoto to hang or crash.
Since it can be easy to lose track of what photos are stored in which library, iPhoto Library Manager can analyze your libraries for duplicate photos, showing them to you side by side and letting you get rid of extra copies of photos that you no longer need. This duplicate analysis is also used when merging libraries and copying photos, to help prevent importing multiple copies of a photo into a library in the first place.
