Dictionary Database Sites

The Consortium for Lexical Research

The web site contains information and pointers to non-free machine-readable databases. The ftp site appears to contain some freely-available machine-readable dictionaries.

Internet Public Library

The IPL contains pointers to many on-line resources. These pointers are searchable. For example, you can try to find all of the pointers to dictionaries.

SIL's page on Linguistic Data Resources contains a useful section on “Dictionaries, Lexica, and Lexical Resources”.

Lexicog is a forum/list on various shades of lexicography, with a browsable archive containing pointers to various resources, dictionary databases included.
