Welcome school learner who really wasn't expecting it to be like this. Welcome student scrolling through Twitter. Welcome person who doesn't want anyone to know what you're working on. Welcome diligent journalist looking at a cached web page from 2006. Welcome parents in with the kids to see an exhibition (sorry about the tempting shop). Welcome all ten people who think they've got the most niche interest in the whole building. Welcome librarians from everywhere. Together we've got this.
