This snapshot of the Trove raspberry pi was taken at lunchtime on Wednesday 17 September 2014. As the hours tick through the day, the locus of Trove use shifts from east to west. At any time, day or night, 365 days a year, between 700 and 800 people are searching Trove, arriving from multiple destinations - Google, Wikipedia, Facebook, Twitter, AustLit, and many other services - and taking different paths through Trove content.
We keep our users front and centre, making them central to everything we do. If you visit the small Trove support team at the National Library - around 13 people in total, not an army - you'll see what we see every day when we walk in the door. We try very hard to maintain a firm focus on those who are using Trove, engaging with them, learning and delighting with them - because we know that word of mouth or its digital equivalent is probably the best way that other parts of our community will explore what's on offer.
But there's another way that I know works.
It's what we - the library tribe - have been doing for years.
We may have the big Trove machine at the NLA but it is you who know what content is of most value to your local communities.
It is you who know what services might appeal to those communities we are not reaching.
It is you who have - as Susan calls it - the market intelligence .
It is you - I hope - who will be honest enough with us to tell us what doesn't satisfy you and your community, or why Trove simply isn't attractive to those parts of our community not yet benefiting.
It is you who know more of these stories - in the hard to reach communities - that might themselves lead more of their fellow community members to explore more. It is you who know whether the teenagers at your local secondary school or their teachers know about this resource.
So I would like to finish by asking you to continue to work with us on this adventure. If you are digitising anything, find out how you can get it into Trove. If you are creating a digital resource - a LibGuide, or an online exhibition - think about cataloguing it so it can be discovered via Trove.
If you hear a good Trove story - tell us!
Even better, be a Trove story-teller for those audiences who have so much to gain from exploring our national heritage, but have not yet found that lush oasis in the desert.
