The GND-ID also allows linking to other editions, encyclopedias and projects that are <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">digitally</hi> relevant in the subject area of <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">edition humboldt</hi>. The BEACON interfaces of these projects are used for this purpose. For example, it is possible to identify thematic overlaps with other projects of the <ref xmlns="http://www.tei-c.org/ns/1.0" target="http://zentrumpreussen.bbaw.de/">Center Prussia-Berlin at the BBAW</ref> via the links in the register data and to make them available for research (example <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://edition-humboldt.de/H0012068?l=en">Wilhelm von Humboldt</ref> or <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://edition-humboldt.de/H0015568?l=en">Friedrich Schleiermacher</ref>). But also external offers, such as <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://www.deutschestextarchiv.de/kosmos/">Hidden Kosmos</ref> or <ref xmlns="http://www.tei-c.org/ns/1.0" target="https://www.deutsche-biographie.de/">Die deutsche Biographie</ref> are linked automatically in this way.
