It would seem a bit excessive to me and i think someone in the discussions i linked to also thought so but who knows As long as webcitation org is only archiving text and not photos video i don t know about the latter given that Terabyte hard disks will become normal within the next year or so it wouldn t put much additional pressure on internet computer resources to do this collectively for all wikipedians for a few hundred million cites and store it on just one single hard disk Personally i ll probably just try and see You can probably make a mental note or note on your user page which journals have a habit of being volatile Online newspapers from places with relatively weak internet access and less developed internet GNU linux communities e g Iraq probably might be volatile in the sense that after a few years they will change software hosting URLs or go offline for whatever reason Another point is that webcitation org probably doesn t yet have a long term reputation archive org and arxiv org have been around for a long time arxiv org has very solid institutional backing and a huge amount of mirroring In any case i don t see why anyone could complain if you archived every cited reference
