Discover the Queenslander is our latest generous interface project, commissioned by the State Library of Queensland to showcase their collection of covers and pages from The Queenslander newspaper. Published 1866-1939, The Queenslander was the illustrated weekend supplement to the Brisbane Courier Mail. This collection includes around 1000 covers, advertisements and illustrations - a beautiful slice of Australian pre-WWII visual culture. Geoff Hinchcliffe and I developed a web-based interface that builds on our previous approaches - rich overview, browsing and visual exploration - and adds some new techniques. Here I'll provide a quick outline; in the following post I will focus on the web framework we used - AngularJS - which I think has some interesting applications for digital collections.
The Mosaic view provides a chronological overview of the collection - each tile represents items from a single year. Like the Manly Images mosaic, the tiles gradually reveal their contents - in this case they are also directly navigable. The Grid view is a more general-purpose explorer for browsing subjects, creators and years as well as colours. Both Grid and Mosaic interfaces link to a detailed item view. There's nothing radically new here - though there are a few new elements that extend on our generous interfaces repertoire.
Inspired by the qualities of the collection images and the related work happening at Cooper Hewitt, Geoff and I were keen to experiment with using colour to explore the collection. The process was (surprise!) more complex than we expected, but ultimately rewarding. Using some palette extraction code that Geoff developed, we first pre-built a palette for each item. These colours are stored in the collection metadata, and act much like any other metadata field. The interface then dynamically builds an "overview" palette revealing the colours in the current set of items, and both the item palette and the overview palette act in turn as filters; rinse and repeat for open-ended colour-browsing. Note also how the filters and facets in the grid view interact; selecting a colour will also reveal corresponding dates, creators and subjects (and vice versa).
This project also introduces some simple personalisation, with the ability to curate and share a collection of favourite items. We opted for a lightweight, no-login approach using HTML5 web storage (essentially fancy cookies) to simply track item IDs. Sharing a collection is a simple as sharing a URL with a list of IDs baked in; and because collections operate within the standard grid view they get filters and facets too.
Finally a little feature that I am particularly fond of is the Trove link on the item page; a simple demonstration of how we might start to link up collections across institutional boundaries. In this case, the State Library of Queensland has high-res images of covers and illustrations, while the NLA's Trove publishes the full contents of The Queenslander (albeit with low-res scans). Using the Trove API we simply harvested the full list of issue dates and corresponding Trove IDs, then matched them against the SLQ items. So each Queenslander item also provides a link to its source issue, providing additional context as well as opening onto further exploration.

Over the past twelve months we have been developing some new approaches to the challenge of providing rich, revealing interfaces to cultural collections. The key idea here is the notion of generous interfaces - an argument that we can (and should) show more of these collections than the search box normally allows; and that there's a zone between conventional web design and interactive data visualisation, where generous interfaces might happen. There's more on this concept in my NDF 2011 presentation, or (in a more formal mode) in the paper I presented at the recent ICA conference.
Here I want to introduce an experimental "generous interface" prototype. Manly Images is an explorer for the Manly Local Studies Image Library - a collection hosted by the Manly Library. This is a collection of around 7000 images, documenting the history of the Manly region from the 1800s to the 1990s. The aim here was to develop a "generous," exploratory, non-search interface to the collection, delivered in HTML.
The original intention here was simply to adapt our CommonsExplorer work into HTML - CommonsExplorer uses a linked combination of thumbnails and title words to provide a dense overview of an image collection. But to "show everything" would mean 7000 elements, a stretch even for modern browsers; and I wanted to experiment with some new approaches to overview which remains the key problem here - a really juicy one. Given 7000 images with titles and little else, how can we provide a compact but revealing representation of the whole collection?
Here, the strategy was to break the collection into smaller segments based on either terms in the title, or date, and to draw each segment as a simple HTML div, where the size of the box reflects the number of items in that segment. These segments also act as navigational elements, opening a "slider" type display for browsing through specific records, and finally a lightbox for larger images, with links to canonical URLs on both Trove and the Manly site.
As a visualisation, it's a bit like a treemap (without the heirarchy), or a reconfigured histogram. But a collection like this is more than a list of quantities; the texture and character of the images is crucial. So as well as showing quantity, the segments become windows revealing (fragments of) the images inside them in a rolling slideshow. We get a visual core-sample of each segment, revealing the character of that group; and across the collection as a whole, a shifting mosaic that reveals diversity (and consistency), and invites further exploration. An interesting side effect is that it becomes possible to surf through the whole collection without doing a thing; it will (eventually) just roll past. This might not be realistic in a traditional browser context, but that traditional, "sit-forward" user model is not what it used to be - as Marian Dork argues, the leisurely drift of the information flaneur might be more apt.
So, a rich exploratory interface to 7000 images, without search, and delivered entirely in HTML; we have shown that it's possible, but is it any good? I'll write up my own evaluation with some technical documentation shortly; meantime, feedback on the prototype is very welcome - and if you are interested in building on it, or adapting it for other collections, the source is up on GitHub.
Finally some acknowledgements: this project was funded by the State Library of New South Wales and supported by Cameron Morley and Ellen Forsyth; thanks to John Taggart of Manly Library for permission to use the image collection. The collection data is harvested from the excellent Trove API, developed by the National Library of Australia.
