 This is a scraper that runs on [Morph](https://morph.io). To get started [see the documentation](https://morph.io/documentation)
 
 * PDFs on the web suck
-* PDFs for realtime information not shared via an organisation's social media / news update channels suck even more
+
+Currently this scraper returns the title, url and year of publication.
+Link text is inconsistent, which makes extracting a complete date tricky.
+However i'm hoping to add this in the future.
 
 Maybe someone can build something useful with this information.
