In addition to creating and switching between libraries, iPhoto Library Manager allows users to copy albums of photos from one library to another while preserving their keywords, ratings, and other photo metadata, or to merge multiple libraries together into one. Library shortcuts provide an easy way to open a library quickly, and iPhoto Library Manager can be used to rebuild or extract photos from a corrupted library.
Along with various bug fixes and minor improvements, new in version 3.5 is the ability to retain faces of people you've identified using the new face recognition features of iPhoto '09 when copying photos from one library to another. Additionally, if you've assigned custom place information to your photos, iPhoto Library Manager will also preserve that data during the transfer.
A single user license for iPhoto Library Manager can be purchased for $19.95 (USD) and provides access to all the features of the program. Basic library switching is compatible with all versions of iPhoto, and all photo copying features require iPhoto 4.0.3 or later. iPhoto Library Manager is a universal binary and requires Mac OS X 10.3.9 or later.
