Antique books on winemaking are as much a passion as winemaking itself for Sean Thackrey, who says he was looking for a classical education about wine when he began collecting texts in 1996. (

There are various places (other than garage sales and Salvation Army stores) where you can get some nice old wine books. According to Sean Thackrey, they are not very hard to get hold of. Thackrey not only collects them, but also translates the foreign language ones and posts them on his site,
wine-maker.net. VERY nice site for people interested in wine-related writings from the past.
If you would like to learn more about old wine books, a nice publication is
Wayward Tendrils Quarterly. They do not have a website of their own but if you check the link, you can find out how to subscribe to the newsletter of the Wine Book Collector's Society. Gail Unselman, who is one of the publishers, is a wonderful person who I am sure would love to help.
