Mayo Co Library plan to restore their 19th century six inch Ordnance Survey maps of the county and make them accessible on their website. These maps consist of 39 sheets that  will be scanned and set up as a combined tile layer on the Map Browser system. This will provide greater acces to the Mayo Library map collection and ill in gaps of areas that were missing. It also will allow users to search maps in great detail and to layer maps on top of each other to track changes in population.
