As the pages were published (on the internet) one would expect that the rights associated with that work would have passed to the heirs of the authors estate. Therefore technically, you would be asking permission of those heirs (if indeed there are any).
If you were to publish it in its orginal form you might be breaching copyright. But then, exactly who might sue you. There appears to be no financial gain involved in this endeavour. So who was it who said "Publish and be damned!"

Of cousre, you might edit/modify some aspects of the webpages, then they would be yours wouldn't they!
