Create a new Document which Summarizes Redactions (in Acrobat 9.0)

If you were headed to meeting with the other side, and you expected some challenges to your privileged and redacted documents, you might want to create a summarized version of your redacted documents to take with you.

This process creates a new, consolidated PDF. Redaction annotations are displayed as call-outs on the document:

To create a summarized document:

1. Open the document containing your redaction marks.
   (You need to run this step before you apply redactions.)
2. Choose Comments—> Summarize Comments
3. The Summarize Options window will appear. I suggest choosing the second option:
   
   
4. Click the Create PDF Comment Summary button.

Setting a Preference to automatically copy selected text into the Redaction Comment

One of the best aspects of how redaction works in Acrobat is that each redaction mark is a standard Acrobat comment. When you double-click on a redaction mark, a sticky note will pop into which you can add your own text:

In the sticky note you might add some information about why you are redacting the information, or even include the text that is to be redacted. Later, when the other side disputes privilege, you can refer to these notes.

Sometimes, it is simply helpful to copy the text you are going to redact into the note itself. That way, you'll know what you redacted when you summarize the document (the last tip!).

Here's how:

1. Choose Edit—> Preferences (Windows) or Acrobat—> Preferences (Mac)
2. Select the Commenting category from the list on the left:
   
   
3. Enable the check box labeled "Copy Selected Text into Highlight, Crossout, and Underline comment pop-ups
4. Click OK

When you select text using the Mark for Redaction tool, the text will automatically be copied into the sticky note:
