Couldn't find a container with that identifier (<b><code>{{ lookup_key }}:{{
lookup_value }}</code></b>). If you think it should be in the catalog, you could
search for an existing record missing that identifier, or create a new container
entity. 
{% if lookup_key == "doi" %}
<p>You can check if it is a registered ISSN-L by visiting:
<b><a href="https://portal.issn.org/{{ lookup_value
}}">https://portal.issn.org/{{ lookup_value }}</a></b>. If this is a valid
electronic or print ISSN, but not the ISSN-L for the container, you need to use
the indicated "linking" ISSN.
{% elif lookup_key == "wikidata_qid" %}
<p>You can check if it is a real Wikidata entity by visiting:
<b><a href="https://www.wikidata.org/wiki/{{ lookup_value }}/">https://www.wikidata.org/wiki/{{ lookup_value }}/</a></b>

<h2>ISSN-L</h2>
<p>The "linking" ISSN for a journal or other publication is one of the 
"print" or "electronic"
<a href="https://en.wikipedia.org/wiki/International_Standard_Serial_Number#Linking_ISSN">International
Standard Serial Numbers</a>, which has been selected to represent the resource
in all media. It is usually the ISSN which was registered first, and defaults
to the "print" ISSN number for a journal. Fatcat uses ISSN-L as the primary
identifier for journals to reduce confusion and potential for duplication. The
ISSN organization publicly publishes a mapping between linking and
print/electronic ISSNs.

<h2>Wikidata QID</h2>
<p><a href="https://en.wikipedia.org/wiki/Wikidata#Items">Wikidata</a> is the
structured, machine-readable database that complements Wikipedia. Entities,
which can include bibliographic entities like books and papers, are identified
by a "QID". Fatcat also links container (journal) and creator (author) entities
to Wikidata by QID. Anybody can edit Wikidata and create QIDs.
