PHYSICAL

• A broken PenBBS 489 - The 489 is a vacuum-filler fountain pen that's one of my personal favourites to use, but the finial has come off. All my attempts to reattach it have failed, but I leave it on my desk and fiddle with it between calls.
• Traveler's Company brass pencil case - my desk doesn't have any drawers, so I use the pencil case to keep track of small objects, such as USB drives, ink cartridges, erasers, etc.
• Assorted books - currently on my desk are Lord Chesterfield's Letters to His Son, Chocolate Wars: From Cadbury to Kraft: 200 Years of Sweet Success and Bitter Rivalry by Deborah Cadbury, Barbarossa: And the Bloodiest War in History by Stewart Binns, and The Right It: Why So Many Ideas Fail and How to Make Sure Yours Succeed by Alberto Savoia

DIGITAL

• LibraryThing - I prefer LibraryThing to GoodReads for tracking and cataloguing my books.
• My own digital humanities project Oxford Dawn. I publish it every other week or so and the topics are based on what I'm reading or researching at the moment.

INVISIBLE

My health.

When I was in my doctoral programme, I realised that my health was crucial. I'm counting it as invisible because when everything is working, one never notices it.
