<pre><span class="line">since last week, BASE (<a href="https://www.base-search.net/">https://www.base-search.net</a>) lets you search more than 200 million documents. The metadata are provided by more than 8,100 repositories and other </span><o:p></o:p></pre>
<pre><span class="line">sources. </span><o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre><span class="line">The main reason for the strong growth is the use of Crossref as another data source in combination with the Unpaywall API and an improved data ingestion workflow.

<pre><o:p> </o:p></pre>
