A technolgoy adopted from Google Books, this now creates a rich historic resource that theoretically takes the leg-work out of visiting the library and trawling through sheets of micro-fische.
So how useful if this service right now?
Clearly USA-orientated, perhaps it needs to broaden its reach of free resources to be of any use to those on a budget in the UK (e.g. everyone now). For example, conducting a search for one of my journalistic heros, Chapman Pincher (the Daily Express defence correspondent who was most critical of the 1970's Labour Government and the Secret Service at the time) reveals only recent articles or resources that require payment and subscription.
