If you live in Rome, New York, you can go to the Jervis Library, built in 1895.
If you live in Norwich, New York you can go to the Guernsey Memorial Library, although the building shown here was demolished in the 1967. The new library looks pretty nice too.
You can also go visit the mammoth Milwaukee Library.
Here are the backs of the cards in the same order. I think they're all clear enough to read as is.
The first card was sent to Miss Persis Davis in Los Angeles. The second one was sent to Alma Tarbox in Harford Mills, new York. I have quite a few cards to and from the Tarbox family.
The last one was sent to Mr. C.P. Robb in Winona, Minnesota.
