Digital Libraries : Challenges and Influential Work

By William H. Mischo

Introduction

As information professionals, we live in very interesting times. Effective search and discovery over open and hidden digital resources on the Internet remains a problematic and challenging task. The difficulties are exacerbated by today's greatly distributed scholarly information landscape. This distributed information environment is populated by silos of: full-text repositories maintained by commercial and professional society publishers; preprint servers and Open Archive Initiative (OAI) provider sites; specialized Abstracting and Indexing (A & I) services; publisher and vendor vertical portals; local, regional, and national online catalogs; Web search and metasearch engines; local e-resource registries and digital content databases; campus institutional repository systems; and learning management systems.
