Discs might be fine but good luck reading one with your kids iPhone.

Yes sure there are probably arcane ways to do it (and your 25 year old CD drive is probably going to die before the discs, assuming you still have a computer that it can connect to...IDE anyone?), but is the OP trying to archive their works, or are they trying to make them easily accessible? They say they want a website so I guess they want something simple and easy to read, and not some equivalent of a dusty archive box locked away in a storage facility somewhere.
