Topic has started to make their recordings downloadable but for the last two years this effort has stalled at 84 albums (for which they now have an advertising campaign with downloadable liner notes) but they promise to do more in the near future.

However, a lot of their early albums are UK issues of Folk-Legacy and Folkways albums for which they probably don't have rights anymore. But these albums seem to be digitally available from Folk-Legacy and Smithsonian Folkways anyway so there's no real reason for Topic to do it too.
