Today I learned a new LaTeX trick. If for whatever reason you want a citation to appear in the bibliography of a document without actually citing it in the document, you can use the command \nocite to force BibTeX to include the item in the bibliography.
Now you may ask why on earth one may want to do this. Wouldn’t such not-exactly-cited citations confuse the readers? Hmm, well, you may be right. But anyway, Google has shown me a perfectly reasonable use of it: you can use this command to make annotated bibliography quite easily.
