Since the publication of the book, further research and remarks from other scholars have caused some corrections in the database. Since maintaining the database in various formats is rather cumbersome, I have decided to restrict myself to the MS-Access database (Version 2000). I will try to update the database as more comments come in or when other errors will be found. This may cause slight differences between the numbers published in my book and the results from new calculations. However, though minor differences with the printed results will occur, the overall picture will remain the same. Within a short time the datasets in .DBF format will be removed.

- Revision of the breakdown in products published
Most of the data sets were in DBF-format: in time I will make the same
data sets available in MS-Access 2000 format only, but the DBF-format is easily
imported into most other systems.
Some of the data sets are
transcriptions of older printed material: they are presented here to make
life a bit easier for other researchers who would like to work with this

In all the data from the Paalgeld portbooks a division is made
between the data concerning the European trade and the West indian trade.
Since no cargo-descriptions are available for the West indian trade, all
percentages for the various goods have been computed from the total
