And we were in the 1,001th or 2,001th year.

So the story was one of evolution.

And that was a big success.

Millennium Book 2 then was

an idea that Princeton University Press thought would be something worth bringing to people.

And the book that you know, Triumph of the Optimists, a fiercely expensive book, which was produced by us, building on something which we had already done in a private publication.

And so a few people around have got the original Millennium Book and Millennium Book 2.

It pops up on eBay from time to time.

The little beginning was once we were into the current century,

And we've had 25 years of running with it.

It's been an amazing journey.

Our data set is primarily a compilation of data.

So let me go backwards in time.

What would we like now?

Nowadays, we have high quality indices.

And so if you start a particular period, we'll go back where there's a good quality capital gains index with an income series.

Nobody would dream of telling you what the return is on treasury bills excluding income because it's a dollar.

The value every year is dollar, dollar, dollar, dollar, dollar.

For equities, people would manage without income, and that's really strange.

So we wanted data which cut us a longer period.
