<p class="Paragraph">Perhaps one of the authors who received a copy of your document made changes but did not record them by choosing <span class="T1">Edit - Changes - Record</span>. You can compare the delivered copy of the document with your original document.</p>
<ul class="L1">
<li class="">
<p class="P2"><span class="T1">Open your original document and then choose Edit - Compare Document</span>.</p>
</li>
<li class="">
<p class="P2">You see a file selection dialog where you can select the copy of the document. Confirm the dialog.</p>
</li>
</ul>
<p class="Paragraph">Now <help:productname xmlns:help="http://openoffice.org/2000/help">%PRODUCTNAME</help:productname> combines both documents in your original document. All text passages that occur in your document but not in the copy are identified as having been inserted, and all text passages that are missing in your original document are identified as deletions.</p>
<ul class="L2">
<li class="">
<p class="P3">You can now accept the "insertions", in which case the relevant texts stay in their original form, or you can accept the "deletions", in which case the marked text contained in the copy are not inserted in your document.</p>
