Photo Library Manager allows you to keep multiple iPhoto libraries in different places on your computer (or even on an external drive or networked volume ) and switch back and forth between them. It also provides at-a-glance information on each of your libraries and allows you to copy photos directly from one library to another, or even merge entire libraries together into one!

Features:
-Create new libraries, and keep track of any number of libraries on your machine
-Switch between libraries, either through the main window or the dock menu
-See what albums are in each of your libraries
-Get information your libraries, such as their version, modification date, and size
-View and change the permissions of your libraries, handy for sharing libraries between users
-Extract the photos from a library, even if the library is corrupted
-Rebuild corrupted libraries based on the information in their AlbumData.xml file
-Create shortcut files, letting you open your libraries directly from the Finder (registered users only)
-Copy photos from one library to another, preserving metadata such as names, dates, ratings, comments (limit 20 photos for unregistered users, requires iPhoto 4.0.3 or greater)
-Merge two or more libraries together, preserving all photo metadata and roll organization (registered users only, requires iPhoto 4.0.3 or greater)
-Import photos directly into a library or album, along with various metadata (registered users only, requires iPhoto 4.0.3 or greater)
