<b>Subject:</b> [OLAC-L] Expansion of the OCLC Control Number: test records now available<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">WorldCat continues to grow! OCLC Control Numbers are assigned to WorldCat bibliographic records, including Institution Records. As previously announced, the OCLC Control Number is anticipated to reach 1 billion sometime after July 1, 2013.
<b>The actual date that the number will be reached is unknown; it is now anticipated to be some months after July 2013.</b><span style="color:red"> </span>At that point, OCLC will increase the length of the OCLC Control Number to accommodate a variable-length
number string. <b>If you use and/or store OCLC MARC bibliographic records and the OCLC Control Number, you will notice a change when the OCLC Control Number 1 billion is reached.
</b>Sample files are now available for use in testing your systems.<b> </b> <o:p></o:p></p>
<p class="MsoNormal"><b><o:p> </o:p></b></p>
<p class="MsoNormal"><b>What action should you take?<o:p></o:p></b></p>
<p class="MsoNormal">If you use and/or store OCLC MARC bibliographic records and the OCLC Control Number, you will notice a change when the OCLC Control Number 1 billion is reached sometime after July 1, 2013. You will need to check the systems at your institution
that use OCLC MARC bibliographic records and the OCLC Control Number. You may need to implement changes to ensure those systems will be able to successfully handle the longer OCLC Control Number. OCLC recommends that you ensure your systems are ready effective
July 1, 2013.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><b>Sample files now available for testing<o:p></o:p></b></p>
<p class="MsoNormal">We have made sample files available for use in testing your systems. The files contain sample MARC bibliographic records with expanded OCLC Control Numbers, and are available for download on the OCLC Control Number expansion

<p class="MsoNormal"><b>Format of the OCLC Control Number</b><o:p></o:p></p>
<p class="MsoNormal">The OCLC Control Number resides in the MARC 001 field and may also be stored in other fields. The OCLC Control Number in the 001 field is formatted as follows:
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">OCLC Control Numbers 1 through 99999999:<o:p></o:p></p>
<ul style="margin-top:0in" type="disc">
<li class="MsoNormal" style="mso-list:l2 level1 lfo2">“ocm” prefix <o:p></o:p></li><li class="MsoNormal" style="mso-list:l2 level1 lfo2">oclc control number, 8 digits, right-justified with leading zeros
<o:p></o:p></li><li class="MsoNormal" style="mso-list:l2 level1 lfo2"><i>A blank space as the last character</i><br>
<b>Example</b>: ocm00012345 <o:p></o:p></li></ul>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">OCLC Control Numbers 100000000 to 999999999:<o:p></o:p></p>
<ul style="margin-top:0in" type="disc">
<li class="MsoNormal" style="mso-list:l3 level1 lfo3">“ocn” prefix <o:p></o:p></li><li class="MsoNormal" style="mso-list:l3 level1 lfo3">oclc control number, 9 digits<br>
<b>Example:</b> ocn123456789 <o:p></o:p></li></ul>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">OCLC Control Numbers 1000000000 and higher:<o:p></o:p></p>
<ul style="margin-top:0in" type="disc">
<li class="MsoNormal" style="mso-list:l0 level1 lfo4">“on” prefix <o:p></o:p></li><li class="MsoNormal" style="mso-list:l0 level1 lfo4">oclc control number, 10 or more digits<br>
<b>Example:</b> on1234567890 or on1234567890123 <o:p></o:p></li></ul>
<p class="MsoNormal" style="margin-left:.5in"><o:p> </o:p></p>
<p class="MsoNormal">In the 035 field, the OCLC Control Number is usually stored with the prefix (OCoLC) and without the “ocm,” “ocn” or “on” prefixes; for example: (OCoLC)1234567890.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><b>When this change takes place<o:p></o:p></b></p>
<p class="MsoNormal">The “on” prefix will be used to identify OCLC Control Numbers that contain ten or more digits. Eight- and nine-digit OCLC Control Numbers will continue to use the “ocn” or “ocm” prefix as described above. The update to the OCLC Control
Number is backward-compatible so that previously defined OCLC Control Numbers will not be impacted. Previously assigned OCLC Control Numbers will continue to work as before.<o:p></o:p></p>
