I bought this book at the Shelburne Museum in Vermont in 1977 and have read it almost cover to cover. If you love needlework history and samplers like I do, you'll consider getting this book as an unusual resource for your library. The Society of Colonial Dames helped Ethel Stanwood Bolton and Eva Johnston Coe put together this huge tome by compiling over 400 photos and scraping up descriptions of 2,500 samplers from the time frames noted by the other reviewers. The authors include almost 130 photos but they're very hard to relate to or appreciate because they're b&w. However, the great lengths the authors went to to make up for this is astounding: they describe each sampler to a T. I included in images above the cover and 2 typical pages.
To the extent any of the info is available, the authors list the fabric, threads, stitches, subject matter (house, mourning, etc.) and, of course, the names, ages and dates of the sampler makers. Reading through the descriptions, I started to make out patterns and singularities. You can find samplers made by boys, made by girls as young as 3, and analyze the text or verse. Did you know that with the large families in colonial times, they sometimes "recycled" names? If little child #2 named Martha died at 6 months, her parents might name child #7 Martha. You can discern the marriage ages, rate of child-bearing (6 kids in 8 years!), unfortunately high death rate both in childbirth and infants. It's interesting to see not just dads, but moms also frequently named their daughters after themselves. These are other books on samplers you might enjoy for further discussion and, especially, close-up color pictures:
