Not many people know this. But not many people know about artists' books and even if they do, not so many people know that they can go to public institutions, museums, university and other libraries who have such things in their collections and ASK TO SEE THEM!
If you're a fan of
contemporary art, you can see, up close, examples from the hand of
super-famous artists like Matisse - his magnificent livre d'artiste Jazz for instance, a copy of which is the Victoria & Albert Museum Library - and also from not-so-famous ones like, ahem,
me. By the way, the V&A Library has quite a few bookworks of mine and gave me an exhibition in 1990.
Public collections are exactly that: open to the public. They may
have different rules for accessing items, but nothing off-putting. The
brilliant British Library in London, for example, asks that you register
for a reader's card if you want to consult the Library - not a problem!
Go and check out work of mine (quite a lot of it) in their
collections, including recent acquisitions described at that link.
