From the BL’s Digital Scholarship Blog:
Users of the British Library’s online catalogue may have noticed that some digitised collection items are now displayed in a new viewer. The new viewer, built with the ‘Universal Viewer‘ software and community and using the IIIF standard for image interoperability, makes several new features available to readers.
New features include full-text search within collection items (where automatically transcribed text is available), navigation by thumbnail images, the ability to copy the direct link to share or bookmark an item. Usage terms are included in an expanded ‘About this item’ panel, and you can download selected items as images or PDFs. Some items can also be embedded in web pages, such as blog posts, teaching resources or news articles. Better zoom and rotate functions improve the experience of large-format items, and the viewer will soon provide a better ‘responsive’ experience for mobile and tablet users.
