N.B.: I want to point out that I preferred to insert only few links in this section rather than making out a long list (which, in my opinion, wouldn't had made sense and, on the contrary, would had generated confusion) to give to the visitors of this page only some starting points for their researches on the classic world on the internet. Of course there are many more interesting sites on the net with the classic world as subject but, again, this page gives only some starting points. Anyway if you want to indicate me some interesting site which, according to you, deserves to be put on the list, let me know by writing to this address: info@locriantica.it.
The links to two of the old web projects, Argos and A.R.G.E., have been deleted from the following list since the projects have been suspended due to the lack of funds.

 
This site, created and maintained by the TUFTS university, is (as it's written on its home page) an evolving digital library and its purpose is to offer the access to the sources of the classical knowledge to an audience as larger as possible, taking advantage of the potential of the internet. And, as a matter of fact, inside the site, as well as many other collections, it's possible to find the complete works, in Greek and/or Latin text of many authors of the classic world; and every single word of the original text has been grammatically analyzed allowing the visitors, simply by clicking over it, to receive detailed grammatical notes on every single word. There are also many images of the classical artistic heritage and the geographical references of all the most important places of the classic age, with their history and the images of many archaeological sites.
According to me one of the best sites (if not the best) about the classic world.
 

A site made by the Superintendence for the Calabrian Archaeological Heritage rich of information regarding the archaeological sites of the region which can be discovered with a virtual tour and many more multimedia resources offered by the site. Every archaeological area can be reached by a dedicated link which will grant the access to many descriptions and historical notes; also, an entire section of the site has been dedicated to the National Museum of Reggio Calabria, which can be virtually visited following a path identical to the real one as can be seen on the maps of the museum shown on every page. In Italian and (partly) in English.
 

This website offers the access to the works of over 50 Latin authors with the original Latin text but without any translation. The site is updated often enough with the addition of new texts.

This site is the result of a special project, made under the high patronage of the Italian Institute of Ancient History, and originally hosted by the University of Bologna which gives to the visitors hundreds and hundreds of web links, sorted by subject and geographical area, to sites whose subject is the study of the Greek-Roman antiquities. From the 2005 the site is hosted by the University of Calabria which, as the new curator of the project, offered its own computer science infrastructure to continue the project work. In Italian.
