<strong><i> NOTES FROM NCAS EDITORS: </i></strong>
<i> </i>
<ol>
<li>
<i>The term "passim" after a range of pages means "scattered"; that is, the indexed item is referred to in a number
of places in the page range, with gaps of various extent between successive references.
</i>
<p>
</p></li>
<li>
<i>The large number of entries under "Radar" and "Sightings", and the possibility of confusion due to multiple
indent levels of sub-entries, led us to create separate sections for those topics. They appear at the appropriate
alphabetic locations. </i></li></ol>
