Long term trade data request Can anyone recommend a resource for very long term trade data? (1500-2014). I have looked and found bits and pieces here and there but haven't come across any single data-set covering all of it. I am thinking of mashing my own together but I really do expect it to have been done already.
Max Roser (2014) – ‘International Trade’. Our World in Data provides data on overall international trade growth during the requested time period, citing  as their sources:


International Historical Statistics (by Brian Mitchell)
Correlates of War Bilateral Trade (as mentioned in the comments)
The Maddison Project (which I love)
The Rise and Fall of World Trade, 1870-1939 (2003)
The contribution of intercontinental trade to Europe’s expansion (O'Brien 1982) (Which I could only find a discussion of)


and many other sources...

I also enjoyed Trade and Empire, 1700-1870 and Sailing Away from Malthus: Intercontinental Trade and European Economic Growth, 1500-1800

Hope those help!
