Digital collections are inherently vulnerable to degradation and decay at a speed much faster than paper. To ensure the material lasts hundreds of years, digital preservation specialists must monitor and take action to prevent digital loss. These specialists monitor what types of file formats people are using (., PDF, WPD), plan for changes in technology and create multiple copies, which are stored in climate-controlled vaults. We also make sure that the content of the files has not changed over time. Given how fast technology changes, we are always thinking ahead to prevent losing these treasured collections.
