This does not detract from the value of online availability for such an essential resource. Navigation and searching within the text are easy to learn without reference to written instructions, which are available for more complex retrieval strategies.

Searching and loading speed are satisfactory for a site that contains the large files attributable to contemporary Web design. A remarkable step in the development of online research material.
Acquisition is justified for all institutions with an art audience.
