Europeana has integrated the newspaper viewer developed by The European Library into the main Europeana portal. You can see an example here:
Now within Europeana you can view OCR’d text next to high-resolution zoomable scans of the newspaper. You can even leaf between the pages. Mark an OCR’d word in the full text and the viewer zooms in on the relevant area of the page. Just double-click on an area of the page to zoom in.
Next update should also allow full screen view, as is already possible directly on the The European Library site, which has now been further improved based on the usability testing.
