Molecular Databases for Protein Sequences and Structure Studies [PDF ebook] 
An Introduction

The amount of molecular information is too vast to be acquired without the use of computer-bases systems. The authors introduce students entering research in molecular biology and related fields into the efficient use of the numerous databases available. They show the broad scientific context of these databases and their latest developments. They also put the biological, chemical and computational aspects of structural information on biomolecules into perspective. The book is required reading for researchers and students who plan to use modern computer environment in their research.
