Sadly the years 1985 to 1991 are not available.
In some years where the original scrapbooks span two books for a particular year there may be more than one file available. Once you have navigated to the year you wish to view just click the scrapbook cover image and the file will open in a new tab in your browser. All the files are in PDF format so you will need a PDF Reader to view them. A link to Abobe Reader is provided for you to download the free app should you need it. Have fun.
