Laws made categories from A Battles, ie A1 Brave Wolfe to Q Humorous and Miscellaneous songs, ie Q38 Building Solomon's Temple with 20 or 30 songs in each category. He did not give the words to the songs - just the reference. But you can find at least one example of each of Laws songs in the Digital Tradition (that project took me a couple of years to track them all down). One problem with Laws scheme was that a song must be put into only one category, while its content might fall under two or three, say a murder ballad involving a Black sailor, that could have fit into F (murder), I (Negro songs), or K (sailor).
