Past Perfect is excellent when you finally want to catalog the entire archive collection. I suggest you read the chapter on Archives carefully, it is quite different from the other catalogs. While leaving what has already been cataloged in place, you can very simply add to the end of the object ID numbers used, and link to the collection either by using the container list, or by multi-level linking(button on right of screen.) Be sure to record the location, that will be a big help, and you can also link items together by using the Relationship screen, along the left side of the screen. I have used a single object ID to cover the entire collection, then add ID numbers as I find specific items that are especially important to the collection. It need not be in any order, but be sure to record the location, even down to the folder, and to record subjects and people. HINT: before doing anything, download the trail version and use that file, not your museum file, to learn how to use PP components like the multi-level linking and the container list. You can leave the trial version on your computer and use it to test our new things you’re learning. Write back if you need more help. And don’t forget the Knowledge Base on their website, and that you can always call them with questions, they are very friendly and easy to talk to.
