Resumen
In this article, the authors put together a collection of authors, who give a glimpse of Digital Libraries projects reflecting the needs of their countries. There are pieces analyzing the challenges of interoperability, dissecting the progress in multilingual systems and inspecting the latest results in interfacing and text-searching technologies. Digital libraries can be among most complex and advanced forms of information systems. Linking the world's diverse intellectual and cultural collections can lead to deeper understanding and wider cooperation. The general problem of linking different systems is called interoperability in the digital library community. Linking multiple systems in a useful way requires various levels of interoperability. Their intention here is to collect a set of brief descriptions of wide-ranging projects highlighting interoperability challenges at all levels. The range of possible solutions for the problem of interoperability is to adopt international standards, integrate all special types of information, provide multilingual support, supporting local and national needs and describe designs and techniques to build digital libraries meant for universal use.
