The first proper 'cycling guide' to Northern Ireland was published last year. I've always cycled. Even when it was deeply unfashionable. I couldn't drive until I was in my mid 20s. I never really found the need for a car in a city.
An interesteing job I did a few years ago for a small 'boutique' imprint. Books are always interesting by their very nature but this also involved a bit of detective work with a ruler an old Linotype Catalogue.
