    What you can do is use the Custom Fields section in the Write Post page to add “metadata” to a post. For example, in the Key field I would write Source, and in the Value field I would post the source URL or bibliography.

    You can then write a plugin that uses the get_post_meta() function to see if a particular post has Source metadata and use the the_content hook to display the source at the end of the post.

    I’m sorry for sounding intimidating, but I don’t know of any plugins that do that. Actually, the half-plugin that I’ve written is called “Match Scores” which does a similar thing (plugin unpublished at the moment). It adds a form to the Write Post form and prompts for football team names and scores for a match. It then hooks into the_content and format the scores nicely.

    If you like, I can send you a copy of what I’ve written in the plugin so far and maybe even customise it for your purposes. If you’re interested, drop by me at and send me an email if you have a Wikipedia account, or an IM if you don’t.
