Several years ago, LacusCurtius‘ Bill Thayer started to put online some articles from scholarly journals. He called this section of his website the Antiquary’s Shoebox, and every now and then, he adds to it. The articles may be a bit old, but at least you do not need an expensive JSTOR account.
If I have counted correctly, it now contains 140 articles. The latest contributions are on seven places in Italy called Ferentum and Ferentinum and on Roman Milestones and the Capita Viarum (which also deals with more than one place called Nuceria). Finally, it’s a somehow reassuring thought that someone has written an article on The Roman Craze for Surmullets.
