No, sadly you can not. You have to buy them in print. Several of Robert Charles Anderson's books are only available in print. These include the Great Migration Directory, The Pilgrim Migration and The Winthrop Fleet. You can not access them online. You can access his older books online for example The Great Migration begins and the Great Migration to New England series. But these don't contain the same data. The other thing are his newsletters. He has 25 issues of his newsletter (which ends this year). This is like his own private journal and includes his latest findings. You can buy that in print you or can subscribe and download the whole lot in PDF. But they don't show up on AmericanAncestors web site either.
