I've just been to visit the first stop of the Brooklyn Art Library's Sketchbook Tour 2012, in the home of the library itself: Williamsburg New York. 
It was a gloriously sunny day, and I wandered in, got myself a library card, and browsed some of the delightful sketchbooks on offer. There were so many! 
Of course I checked that my own sketchbook (you can see some pages from it on one of my previous blogs) was there safe and sound, which was a great feeling. 
The sketchbooks will be in Brooklyn for another few weeks, and then off around the States, and in London in November. You can check the dates on the website. Hope you'll make it!
