It's the Digital Tradition database, which is kept here at the Mudcat. Unlike the Forum, it's a static database which is periodically updated; the Forum changes continually, of course. When looking for song lyrics and information, you need to search both. This is easily done through the online search engine, which you will see at the top of every page. Remember that song titles vary and that people often also get them wrong or mis-spell them, so it's generally best to search for a characteristic phrase which you remember.

When a song is already in the DT, it's usually best, when answering a request for it, to give a link to the existing file rather than copy-and-pasting the whole thing into the thread; this can lead to later confusion and time-wasting, not to mention duplicate entries in the DT. For those who don't know how to make them manually, links can easily be made using the "make a link" feature below the "reply" box on each thread page. The DT file for this song is at SILVER IN THE STUBBLE.

There is a great deal more information in the FAQ, which a lot of people never look at.
