<p class="MsoNormal"><span lang="EN-US">Dear Sir or Madam, <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">As a member of the committee responsible for the German-speaking countries (Germany, Austria, Switzerland), the “<a href="https://wiki.dnb.de/display/STAC/AG+Alte+Drucke">Arbeitsgemeinschaft Alte Drucke beim Standardisierungsauschuss
der Deutschen Nationalbibliothek</a>â€, I have the following question for you: <o:p>
</o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">In the German union database <a href="https://en.wikipedia.org/wiki/K10plus">
K10plus</a>, superscript and subscript numbers and letters that can be recorded using Unicode have recently been permitted. This now enables us to specify these when writing collation formulas as part of the cataloging of Early Printed Books. There should be
no problems when exchanging data. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">We do not see any problems with superscript and subscript numbers in this regard. However, there is still some doubt about superscript letters, as these originate from different Unicode blocks* and are not represented
uniformly in our union catalog. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">A German-language overview of the numbers and letters to be used can be found here:
<a href="https://verbundwiki.gbv.de/download/attachments/201228317/Signaturformeln_Unicode.pdf">
https://verbundwiki.gbv.de/download/attachments/201228317/Signaturformeln_Unicode.pdf</a>.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Our question is whether you in English-speaking countries also use Unicode when entering collational formulas – especially for superscript letters – or whether you use a different character set (which one?).
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">As we have been able to ascertain, the use of superscript letters in collational formulas is permitted according to the DCRM (see
<a href="https://bsc.rbms.info/DCRMR/phys-desc/Note-on-extent-of-manifestation/#621544-signatures">
6.215 — Note on extent of manifestation - DCRM (RDA Edition)</a> under 6.215.44.3).
