"Redaction is the careful editing of a document to remove confidential information.
The Microsoft Office Word 2003 Redaction Add-in makes it easy for you to mark sections of a document for redaction. You can then redact the document so that the sections you specified are blacked out. You can either print the redacted document or use it electronically.
Sensitive government documents, confidential legal documents, insurance contracts, and other sensitive documents are often redacted before being made available to the public. With the Word 2003 Redaction Add-in, users of Microsoft Office Word 2003 now have an effective, user-friendly tool to help them redact confidential text in Word documents."
The redacted document can be protected and saved. The add-in creates a copy of the original, so original material is still available.
