How does COCOA increase the amount of indexing and searching of copyrighted materials?
First, as noted elsewhere, COCOA does not prevent indexing or searching or the display of text snippet search results. But it will increase it. Here’s how: Currently, indexing/searching is inextricably tied to displaying page images. Thus, if a copyright owner keeps their work out of a CDS (for example, because they feel it shows too many pages, not because of the indexing), that book is no longer indexed or searchable at all. With COCOA, a book could be entirely indexed, entirely searchable in terms of reporting what page a word or phrase appears on, and even showing that in a text snippet, but, if it’s the copyright owner’s desire, not have the page image be displayed. In fact, it’s possible books could have 0% of page images available but be made searchable. COCOA allows decoupling indexing/searching vs. page image display in a way that is not now possible. Thus, substantially many more books could be indexed and made searchable, if only the copyright owner had control of page image
