The Wellcome Library has released a digital asset player and timeline software.
Here's an excerpt from the announcement:
What does it feel like to interact with a digital version of a book? How can we replicate the experience of working with physical collections&—on the web? What features will enhance a researcher's experience of using digital collections? . . .
We asked these big questions, along with innumerable others, during the development of the Wellcome Library's "digital asset player" and interactive timeline. Now we are offering the player and timeline software to you.
