<h3>Selecting an edition</h3>
<p>
MARC records are associated with unglue.it edition records. Look for links in the "more" tab of any unglue.it work page that has a "Download" button on it.
{% endif %}
<h3>Adapting records from LoC</h3>
<p>
For ebooks which have existing print editions cataloged in the Library of Congress, we can automatically convert those to Unglue.it ebook MARC records, which will then be automatically affixed to the ebook edition in our database and <a href="{% url marc %}">provided to ungluers</a>.
</p>
<p>
To get the XML record, search <a href="http://catalog.loc.gov/">http://catalog.loc.gov/</a>, select the print edition, and click on the permalink (will look something like <a href="http://lccn.loc.gov/63008219">http://lccn.loc.gov/63008219</a>). This page has a MARCXML link.
</p>
<p>
The record loader will automatically add links to all the unglued ebook files known to the Unglue.it database. <I>Make sure those links are in the database before adding the record.</i> </p>
<h3>Editing stub records from LoC</h3>
{% if form.initial.edition %}
The current records for this edition are here. They may be auto-generated stubs:
<div id="libtools">
<form method="POST" id="record_form" action="{% url marc_concatenate %}">

<input type="hidden" name="edition_{{form.initial.edition}}" value="on">
<input type="submit" name="submit" value="Download MARC" id="submit">
</form>
</div>
{% endif %}
<p>
Edit the record, then upload it as a "record prepared for Unglue.it". The record loader strips 001, 003, 005, 006, 007, 856 and >900 fields, and adds them back in on download.

<p>
The robot cataloger will automatically add links to all the unglued ebook files known to the Unglue.it database. <I>Make sure you have added those links to the database before creating the record.</i> Likewise, it will autofill the ISBN, and you should have already provided that.
</p>
<p>
If you want to add a MARC record for a non-unglued but publicly available book, create a MARCRecord instance in the admin interface and populate its fields there. (This assumes that the MARC record is for the freely available ebook version and exists in a linkable form. If it does not, upload it to S3 first, by analogy with the <a href="http://django-storages.readthedocs.org/en/latest/backends/amazon-S3.html#tests">django-storages documentation</a>, and use that link.)
