Notes:
- as of 22 March 2009
- all words forced to lower case for comparison
- often it is the reference that is wrong, or uses # for non-definition lines
- only "English" words are shown, words with diacritics etc are not
- Finnish entries are ignored because there are a ridiculous number of bad links
- hyphenated words where all components are present are not listed unless explicitly linked
- total of 22001 missing entries
- if you want comments to persist, write to User talk:Robert Ullmann/Missing
