Encoded Archival Description Tag Library, Version 2002
EAD Elements
<ptr> Pointer
Description:
An empty internal linking element that uses attributes to provide for movement from one place in a finding aid to another place in the same finding aid. Unlike the <ref> element, the <ptr> element cannot contain text and subelements to describe the referenced object.
Do not confuse with <extptr> which is used to connect the EAD document to an external electronic object, which is not part of the described materials.
See related linking elements <extptr>, <extptrloc>, <extref>, <extrefloc>, <linkgrp>, <ptrgrp>, <ptrloc>, <ref>, and <refloc>.
While XML Linking Language (XLink) Version 1.0, which is the basis for EAD linking elements, is a stable document, examples of EAD usage are hypothetical and have not been tested in real XLink-based applications. Those wishing to use XLink are encouraged to consult the specification available online at <http://www.w3.org/TR/xlink/>.

This collection was re-appraised by repository staff in 1992 in order to
facilitate use by weeding the collection of materials no longed deemed as
having evidential or informational value. A list of materials removed from
the collection after the re-appraisal is provided at the end of this guide.
