{{umbrella|Notes}}
Since October 2015, we systematically add the sheet count to a bibliographical description. This is the total number of sheets used to print a publication. This number is added in a note of the type 'sheet'.
<blockquote>
'''''Example'''''<br>
448 pages in 16° format = 14 sheets of paper<br>
Note of the type 'sheet': 14<br><br>
314 pages in 12° format = 13.083 sheets of paper<br>
Note of the type 'sheet': 13.083</blockquote>
We always use a full-stop and never a comma, e.g. '10.5' and not '10,5'.
In the case of multi-volume works, we note the sheet count for the total work.
<blockquote>
'''''Example'''''<br>
<nowiki>1#</nowiki> 132.50<br>
<nowiki>2#</nowiki> 147.50<br>
<nowiki>3#</nowiki> 147<br>
<nowiki>4#</nowiki> 144.50<br>
Note of the type 'sheet': 571.5</blockquote>
