DISQUS

OCA charges 10 cents per page -- the $30 figure comes from using 300 pages as the average length of a book. For Google participation, institutions do get their scans back, but there are some restrictions. If you want to see the UVA agreement as an example, go to http://www.lib.virginia.edu/press/uvagoogle/agr.... Not all the agreements are exactly the same, and they were scrutinized a lot.

As to the Internet Archive texts, it is a great resource. But there isn't necessarily any collection development there -- there are many sources, and some texts were contributed by volunteers. Your search may not have been failing, they may have just had vol. 4 and not vols 1-3 and multiple copies of texts may have been contributed. The same is also somewhat true for Google Books -- volumes go in somewhat randomly and there is duplication, but their collection building is based on the collection building at our libraries, so in theory they're aggregating what we thought was valuable, and complete sets where possible. OCA and Internet Archive will get there as the collection grows.

Making of American is great, isn't it? 12 years collaborative collection development and digitization.
