After they upgraded their web archive replay system, we were no longer able to find 49 out of 351 mementos (archived web pages). In part 2 of this four part series, we focus on the movement of a collection from the National Library of Ireland (NLI).

We found that 192 mementos, out of 979, can not be found in Archive-It (i.e., missing mementos).
For example, the memento from the European Archive:
