I doubt that there are any books available at this late date. The title of the book is "GRESHAM, NEBRASKA 1887 - 1987. There is no reference to the publisher nor an ISBN number listed in the book. The closest I can find about the publisher is a picture of the Centennial History Book Committee which includes one person listed as a Walsworth Representative. I can only assume the book was published in 1987 or later.
I purchased my book when in Gresham in the late 1990's. I happened to go into the Gresham State bank to see how I could contact a person I was looking for. It so happened that the person's wife was working there. In our conversation, the book was mentioned and she had a copy in the bank. I bought it. I do not know if they had any more or not.
In searching for the bank's address, I now learn the bank has been sold/merged with the York State Bank & Trust Co. The physical address at the bank is: 405 Elm Street, Gresham, NE 68367. Telephone number is: (402) 735-7277 You might call or write to them to see if the book is still available there, or if they could tell you who may have one available.
Good Luck.
