Permit me to gloat that I have TWO Malvina Reynolds songbooks:

• Little Boxes and Other Handmade Songs, Oak Publications, 1964
• There's Music in the Air: Songs for the Middle-Young, Schroder Music Company, 1976

www.bookfinder.com lists Malvina as author of several books, including a Malvina Reynolds Songbook from Schroder that may (or may not) still be available new from Borders for less than ten bucks.
