It's all there in the archive, all 411 issues of Liberty and Libertas. It's a warts-and-all collection, with plenty of warts. So far, all I've proven is that an individual can produce a free archive almost as sketchy as the big commercial databases. (To really scramble things, however, seems to require much more capital than I have access to.)
Now comes the fun part, figuring out what software to use for the more formal archive, continuing the transformation into a searchable text archive, and starting to make use of all this material that has been so hard to access.
And download, download, download! Squirrel away copies of these things, so that there is never again any question of Liberty not being available to those who are interested in the anarchist tradition.
