    February 2008   For this book I asked artists with varying interests to create a
                    thread of linking Wikipedia articles starting with something
                    they found interest in, and continuing to other topics from links
                    within the page. The results are a group of similar or dissimi-
                    lar topics that are all linked together linearly.

                    There were two initial purposes in this project. The first was
                    to create a small game that explored surfing through informa-
4                                                                                       5
                    tion using keywords. I wanted to explore how within a digital
                    system categories of knowledge have become almost irrelevant
                    in accessing the information they once contained. The Siege of
                    Paris is no longer confined under World History, France, Fran-
                    co-German or Franco-Prussian War 1870-1871 (DC281-326.5),
                    as it is in the Library of Congress. It is just as much a part of
                    French History as it is in the story of the elephants Castor and
                    Pollux, the Paris Commune, things that happened September
                    19, 1870, and balloon mail lore. And it is just as immediately
                    accessible from any of these places, as well as the possibility
                    of ending up in a multitude of other diverse places. Instead
                    of topics organized and accessed by a tree model going from
                    larger branches to smaller ones (World History, French History,
                    etc...), I picture a new model where there are no branches, but
                    a pile of scattered leaves where one leaf overlaps many other
                    leaves. Everything is interrelated. It always has been.

                    The second purpose of this project is to present a list of ideas
                    that reflect the interests of each artist. Ideally, one could be
                    able to use these articles as supplementary to understanding
                    the artist’s practice and work. The exception is with those who
                    chose to use this opportunity to perform a conceptual game
                    about the task itself (like with Brendan Fowler’s contribution).

                    Because of the nature of Wikipedia, many of these articles have
                    been updated since the artists did their initial search. Some of
                    these may even no longer be linked together. And, some may
                    contain errors (grammatical, factual, etc...).

                    I did my own search. I found my way from boredom to balloon
                    mail. In real situation a few years ago in Los Angeles, I found
                    myself a little bored and wandering through a bookstore one-
                    night. I came across a title that caught my attention: Here is
                    Where We Meet. It was a newly released book by John Berger.
                    I opened the book and found a description of trapped Parisians
                    sending distant loved ones letters by unguided balloons. That
                    was the first time I got to balloon mail from boredom.
