A nice stroll to the British Library, by a slightly indirect route that ended up at about 3.4 miles, where I sorted out my reader's card, reserved the first edition of The Struggle For Empire, and had lunch and took a look at the current British Library / Science Fiction Foundation SF exhibition while they were bringing it up.
Spent a couple of hours on a read through and made a few corrections of my scans, nothing very serious, and arranged to have it kept in the reading room for another session tomorrow. After that I visited the book shops on the other side of Marylebone road (nothing terribly exciting unless you're a Twilight fan, they have the books for £2 each), looked in on a few shops in Tottenham Court Road (no bargains whatever), and took the bus most of the way home, walking the last mile or so to visit a couple of shops. The total distance walked appears to be 5.8 miles, which will hopefully make up for the chicken and bacon sandwich I had at the museum...
