To CONSER/BIBCO operations representatives and PCC standing committees:

Over the past few weeks, OCLC staff and other members of the Provider
Neutral Task Group on e-Monograph records have discussed adding an option
to PCC provider neutral guidelines at OCLC's request. The option allows
use of a subfield within the 856 field to identify the provider to which a
particular URI applies. The request was originally raised by providers
OCLC is working with, such as HathiTrust, and is also driven by a need to
label URIs in WorldCat Local displays. Various subfields of 856 were
discussed (including $a, $n, $y, and $3), before finally settling upon $3
as the best for this purpose.

This option maintains a provider neutral base record for PCC, yet allows
further identification of URIs that are already unique to specific
providers in the 856 fields. It is expected that OCLC will be the primary
user of this option, but it may be used by others following PCC provider
neutral guidelines.

The wording to be added to PCC provider neutral guidelines for
e-monographs, e-serials, and e-integrating resources is:

*** ***856 $3 may be used to specify the part of the described material to
which the field applies, and/or the name of the provider or collection. In
the latter case, prefer to use only when the domain name in the URI is not
specific. Exception: In some instances, OCLC still needs to use the name
of the provider or collection in the $3 to accommodate their internal
manipulation and display needs, even when the domain name is
clear. Placement of the $3 can be either before or after the $u , OCLC
will always place the $3 before the $u. If found in existing records,
please do not remove it.

An example is from OCLC #471697923:

856 40$3 NetLibrary $u

We would like to update provider-neutral documentation with this option as
soon as possible. If you have comments on this please send them to me by
Dec. 17th, 2009.
