There are many requests for lyrics posted to MUDCAT, most receive
excellent responses.
I thought it might be useful to mention some online sources for lyrics
which may be of interest to folks on this list.

FOLK & BLUES
Smithsonian-Folkways http://www.folkways.si.edu/index.aspx
Most FOLKWAYS albums contained booklets with lyrics to the songs - these are now available as PDF files online at the Smithsonian website.

BLUES LYRICS
A series of books containing the lyrics to the DOCUMENT and YAZOO
albums was published some years ago. They are now out of print,
the author, BOB MacLEOD, died and there is no indication that the
family plans to reprint the books. Perhaps some member of the list or some libraries have copies.
Perhaps some enterprising soul out there would consider obtaining rights to the books and publish them on a CD-ROM, searchable and printable.....

MUSIC HALL

Perhaps others on the list can provide additional sources.
Best wishes, Thomas.
