They are NOT available that I can see online, but this might be useful for either folks who are in NY (Syracuse area) or perhaps an arrangements can be made online.

From the site:
"This collection consists of 373 patterns drawn to scale and finished with watercolor paints in order to imitate the colors of the actual quilts upon which the representations are based. Although the patterns were completed from 1919-1923, many were based on quilts made before 1850 and are thus an important record of domestic life from that time. This collection consists of 373 of the original 419 patterns donated to the library."
