There is no complete textbook on Information Integration so far.
Fortunately, Michael Genesereth of Stanford University has written a book
Data Integration - The Relational Logic Approach ,
of which an online version can be accessed.

Background information on the theory of relational databases can be found in the book:
Serge Abiteboul, Richard Hull, Victor Vianu. Foundations of Databases. Addison-Wesley, Reading, Massachusetts, 1995.
The book is available for download at the Technical University of Vienna:

In addition to the book, several research papers contain material that is complementary to the content of the course.

Several companies offer
open source systems for data and information integration.
