To archive or what?

My question to the Forum refers to what to do with my Mums extensive boxes of slides.
My Mum has been an avid and very good photographer for over 50 years. She has been a lifelong member of Doncaster and Ringwood Camera Clubs and a few years ago began the Phillip Island Club. Mum is still shooting away but I would like to know what are the options in storage. Destruction is not an option as there are some beautiful images.
What have other forum members done?
Scan and archive seems like a good idea, but very time consuming. There must be thousands of images.
It would be great to hear some thoughts, thanks
