<p>Entering an <a href="https://musicbrainz.org/doc/Edit_Note">edit note</a> that describes where you got your information is highly recommended. Not only does it make your sources clear (both now and to users who see the edit years later), but it can also encourage other users to vote on the edit — thus making it get applied faster.</p>
<p>Even just providing a URL or two is helpful! For more suggestions, see <a href="https://musicbrainz.org/doc/How_to_Write_Edit_Notes">the MusicBrainz guide for writing good edit notes</a>.</p>
