The two paperback books called Toy and Miniature Sewing Machines: An Identification and Value Guide (Part-I and Part-II) by Glenda Thomas are an excellent resource for toy sewing machine collectors. Each machine is illustrated in full color, covering the years from 1870 through 1980. No toy sewing machine collection is complete without these two encyclopedic volumes.

The paperbacks are available on Amazon.com via third-party sellers. Prices range between $20.00 and $60.00.

Part-I was released in 1994. Part-II was released in 1997.
