This document discusses how to add links to digital objects in EAD finding aids. It explains that <dao> tags are used to embed images for display or link to files. <daogrp> tags can group two or more related digital objects together or link to thumbnail and reference images. Links can also point to objects not directly part of the archive collection using <extptr> tags. Examples are provided of XML code for embedding images, linking to files, grouping objects, and linking thumbnail and reference images.
