[Evergreen-catalogers] Expansion of the OCLC Control Number: test records now available: Problems with searching for 10-digit OCLC numbers

[Hardy, Elaine]

I tested in 2.3.6 some time ago and was able to search all the OCLC
numbers. I have not  tested recently or in 2.4 yet

records now available: Problems with searching for 10-digit OCLC numbers

 

Has anyone else had trouble searching the 10-digit OCLC number in the OCLC
Control Number test record sample? We can find records with the 11- and
12-digit numbers by identifier (id:) or selecting ISBN/ISSN/Other, but
cannot find record with the 10-digit number (on3987654321).

 

Thank you,

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. The actual date that the number will be
reached is unknown; it is now anticipated to be some months after July
2013. At that point, OCLC will increase the length of the OCLC Control
Number to accommodate a variable-length number string. 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.
Sample files are now available for use in testing your systems.  

 

What action should you take?

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.

 

Sample files now available for testing

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 website
<http://www.oclc.org/batchload/controlnumber/number-expansion.en.html>
(http://www.oclc.org/batchload/controlnumber/number-expansion.en.html).

 

Library staff who may need to be aware of this change include:

.       Cataloging and IT librarians who download OCLC MARC bibliographic
records to the library's local system

.       Resource sharing librarians who use third-party ILL management
programs that store or use the OCLC Control Number for searching

.       Reference services librarians who use WorldCat Local to help
patrons locate items. 

 

Publishers, vendors and others that partner with OCLC who may need to be
aware of this change include:  

.       Integrated Library Service (ILS) vendors that use OCLC MARC
bibliographic records to test compatibility with OCLC     

.       Publishers, material suppliers and electronic content providers
that use OCLC MARC bibliographic records in their systems  

.       Developers who maintain services that use the OCLC Control Number.

 

Format of the OCLC Control Number

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: 

 

OCLC Control Numbers 1 through 99999999:

*	"ocm" prefix 
*	oclc control number, 8 digits, right-justified with leading zeros 
*	A blank space as the last character
Example: ocm00012345 

 

OCLC Control Numbers 100000000 to 999999999:

*	"ocn" prefix 
*	oclc control number, 9 digits
Example: ocn123456789 

 

OCLC Control Numbers 1000000000 and higher:

*	"on" prefix 
*	oclc control number, 10 or more digits
Example: on1234567890 or on1234567890123 

 

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.

 

When this change takes place

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.
