Add sources at bottom of the post?

Hi there,

I run a blog and I like to print the sources of my information at the bottom of each post with the title linked to the original source (in the form of “Source Article Title [source]“). Sort of like footnotes without the little numbers.

What I would like to achieve is a way to style these sources, which I can do fine with CSS.

Does anyone know how it would be possible to add a field in the “Write” page that would take whatever is in the field and apply a certain style to it? Is there a Plugin that exists? Is it possible with Custom Fields?

Any advice would be helpful.
