Resource preservation as a way to combat "link rot" is a desirable feature. For academic purposes it allows resources to be (more) permanent for research, citation, and referencing. For non-academic uses, it allows a resource to be available even if the original has been moved or removed.
Examples of services:
- users may not know who Perma.cc or Archive.org are and may not be comfortable using them.
- there's an issue about ownership of content using these services. Ownership and agency is important to coops.
- using perma.cc, IA etc. should be an option, not the default. This way the resource contributor can decide for themselves what is best.
- what if service agreement with perma.cc ends? How do users control their duplicated content in that case?
- how are revisions to original content maintained if perma.cc etc. are used? Will the user require to manually update copies, or is it automatic?
