Any combination of opisi and dela may be ordered at one time. The opisi are essential keys to the Archives, and many libraries will wish to make the complete set available to their users. 450 reels are already available. The total number of opisi reels is subject to final confirmation. Those wishing to place standing orders for parts of the collection are invited to discuss their requirements with Chadwyck-Healey.
