This page gathers linguistic resources from all around the world and is available in several languages: Dutch, German, French, Portugese, Spanish and Afrikaans, Norwegian. This is a very comprehensive gathering; along with dictionaries, access is also provided to many literature resources and text projects. I even found a Middle English dictionary (word searches here take you to texts in which your word is used) and a technical terminology dictionary. I used SGML as a test-it quickly yielded several definitions. Many of the sites provide access to audio resources, which can be downloaded and used on your local system.
A real effort has been made to represent as many languages as possible, but the available resources vary widely. One inherent problem comes with how Web browsers deal with non-Roman characters. There are helpful links to sites that provide font packages that can be downloaded.
This is a very helpful, comprehensive site. Although you can't do a keyword search for a language, an alphabetical index is provided that gets you to your desired language quickly. I found myself happily moving from one site to another: I had a hard time just using one site, then leaving. Something else would catch my eye, and off I'd go.
This page contains no large graphics, and is generally easy to access. But since this page is basically a collection of links, access to the various language resources can vary widely. And access is provided to a variety of formats: from Web to ftp. Some sites will load quickly, others may be hard to reach; I gave up on several sites that were taking too long to load. The author considers this a work in progress, and encourages input and information about new resources.
