Location of any Hood River City Directories 1940s - 1950's?

I'm looking for someone who lives in Hood River who can answer some questions for me:

1) Is there a facility in Hood River which has copies of Hood River City Directories from about the 1940's through the 1950's? This could also include 5-4 years earlier. Is the town of Hood River included with any other city in Hood River County or possibly Wasco County? (Directories at the Hood River County Library start in 1992.)

2) Does the Museum, on E. Port Marina Drive, have copies of Hood River City Directories, microfilm of old newspapers and family history information? Is this the best place to do genealogical research in Hood River, or is there another place?

3) Is there is an active genealogical or historical society in Hood River, what is their address and how I can contact someone there? Do they allow research at their facility? Would I have to make an appointment for a visit?

4) Are early phone books available in the Hood River County Library or at the Museum for the 1940s through 1950's?

5) What type of information can I expect to find at the Family History Center at 18th and May Street? Do they just have computers or do they have microfilm and books about Hood River at their location?

My family of interest is Merle CAMPBELL, a policeman, who lived and worked in Hood River. I think he was a sargent.

Thank you for your help.
