Abstract
In the past few years, cloud computing has evolved to be a major trend for all levels of computer users and organizations. This article compares the suitability of cloud computing software for a library setting among some available cloud service providers. The paper first introduces cloud computing with respect to its definition, types, and services. The focus is then shifted to what cloud computing might mean to libraries. The paper also explores the potential cloud based operating system providers, productivity suite providers, mailing service providers, and storage, cataloging, and calendar service providers.
