The Tulip mania is considered to be one of the first recorded examples of a speculative bubble in modern history. Long story short, the newly introduced tulip plant in the United Provinces, combined with the development of the first modern financial instruments like future contracts and markets to exchange future contracts, lead to a craze that suddenly burst in February 1637.
The wikipedia article has the following to say about the available data:
The lack of consistently recorded price data from the 1630s makes the extent of the tulip mania difficult to discern. The bulk of available data comes from anti-speculative pamphlets by "Gaergoedt and Warmondt" (GW) written just after the bubble. Economist Peter Garber collected data on the sales of 161 bulbs of 39 varieties between 1633 and 1637, with 53 being recorded by GW. Ninety-eight sales were recorded for the last date of the bubble, 5 February 1637, at wildly varying prices. The sales were made using several market mechanisms: futures trading at the colleges, spot sales by growers, notarized futures sales by growers, and estate sales. "To a great extent, the available price data are a blend of apples and oranges", according to Garber.
It seems that the work of Garber contains the most extensive data collection. I wondered if there is a place on the net where these data are readily available, preferably in a format that is easy to parse for statistical analysis tools like R.
TL;DR : Can I download the data concerning Tulip mania somewhere?
