What a teasing link you posted Kat - Thanks !
I recently made a swap of a book, a 105 year old book of poetry, of poems stretching back to ancient times and translated from old latin and Gaelic.
I had found it in the shop of a modern art museum and thought it starnge to be on sale.
What I really loved about it was that was signed as a gift from one person to another - so not only the poems had history, so too did the book.
I can't sell or give away books as I like them too much - but the swap was a good one - for a modern book of chineses recipes and coloured photo-plates of ancient drawings and txts.
The swap was biased not really in my favour, but it was with my sister - So I can still see and borrow anytime I want..
Ah to have 25.000 spare !
