To view the searchable data you need to be registered (free). To do this click on create account in the Login form in the bottom left corner of the screen.

Most of the data is made up of text extracted from out of copyright books which I have scanned in. What I provide is the text not the graphics. To see a list of the documents available to search click on the appropriate item in Data Index at the bottom of this article. Alternatively you can just enter a search argument such as "john Smith" in the search box to search across all the documents.

Electronic copies of the documents (including graphics) can be bought as a downloadable PDF eBooks from lulu.com or from youpublish.com.
