For advice on making capsules to bury for a very long time check out the
British Library’s website where they have some information from the National Preservation Office.
Some new libraries in Devon made their own time capsules and buried them under the libraries when they were built.
Ivybridge Library and
Tiverton Library both have time capsules buried under them, wow, just think... in the future someone will dig those up and find out all about the library, what the tickets looked like, what items were being borrowed and even some photos of what the old library looked like.
