Searching within a Book

Here's a tip: If a book does not have a subject index, try searching for it in Google Books. If it has been indexed by Google Books, then you can search within the text of the book. The search results will point you to page numbers on which your search term appears, effectively serving as an index. I did this recently with Acquisition and Loss of Nationality, Vol. 1: Comparative Analyses, a 499- page book with no index. I had the book in hand but I wasn't inclined to read the entire text in order to locate references to "statelessness"!

Amazon.com offers a similar "search inside this book" feature; here's a link to the same book for comparative purposes.
