Abstract:
Recently there has been much effort invested in the creation of digital libraries containing
antique documents, in order both to preserve our cultural heritage and to provide a broader
access to these texts. Often, however, the various collections of documents are isolated from
one another.This paper presents a system, based on the use of XML trees, to federate three
existing digital libraries that contain documents from the Spanish Golden Age (16th-18th
centuries).This federation offers very valuable advantages to a wide community of
researchers, who will be able to access multiple digital libraries (at present time, three)
through a unique entry point. Although we present a very specific system, it is based on a
well-designed architecture that allows the federation of any other digital library based on
databases or XML files. In this paper we also describe this architecture and provide an
overview of an extension of it to federate multilingual digital libraries.
Keywords:
Digital Library Federation, XML trees, user interfaces, emblems.

he Internet has become one of the most important places to publish all kinds of infor-
mation. It is especially important when we consider documents such as rare books, man-
uscripts, and other artifacts of our textual heritage, because their publication using usual
methods is too expensive and not economically viable.These documents are kept in museums
and libraries with historical archives with very restricted access, so their Web publication serves
two purposes: 1) offering them to the research community and 2) preserving them.These docu-
ments, besides their great beauty, are a magnificent source of information about different cultures,
such as in the present case, the Spanish Baroque.Through the analysis of these works, researchers
can find information about morals, habits, technology, education, and other aspects of cultural and
social life that are of interest to a wide range of researchers, including anthropologists, historians,
and philologists. Last but not least, digitization helps to preserve these documents, preventing them
from disappearing as a result of their antiquity and fragility.
With these two goals - preservation and access - in mind, much effort has been directed at
publishing these documents on the Internet, usually in the form of document databases or digi-
tal libraries.We have created two digital libraries, one for Spanish Emblem Books

and one for
the Early Spanish Press.
