# Splitting a library into smaller libraries

If you have a library that has gotten too large and you want to split it into multiple, smaller libraries, there are a couple different ways you can go about doing so.

Copying Albums

First, click the “Create Library” button and choose the location you want to create the second library.

Then, drag one or more albums or events of photos from the album list of your big library onto your newly created library. This will copy those albums over to the new library, including all their dates, ratings, comments, etc. After you have copied the photos to your new library, you can use iPhoto to delete them from the big library, to clear up the disk space in that library. You can repeat this process with small or large batches of albums and any number of libraries to split up your collection into smaller, more manageable pieces.

Duplicate & Prune

Use the "Duplicate Library" command in the File menu to make a copy of the library folder that you want to split. You can then open one copy of the library and move whatever photos and albums you don't want in that library to its trash. Then open the second library and move the rest of the photos into that library's trash. After double checking to make sure that no photos have been trashed from both libraries, empty the trash of each library. This method is useful if you have some items that iPhoto Library Manager can’t copy (e.g. books, calendars, or slideshows) but you want to preserve those items in both of your new libraries.
