An overview of commercial electronic document delivery suppliers and services

There has been a proliferation in commercial electronic document delivery services. Over the past few years this consistent growth, combined with enhancements to existing services, has made it difficult for librarians to keep abreast of the latest developments and service availability. This paper presents an overview of document delivery services and suppliers, and provides discussion on the various types currently available. The paper is further divided into non‐collection‐based services, collection‐based services and specialised collection‐based services. Detailed information about particular services has been collated and presented in tabular form: this includes information regarding cost, delivery time, subject field and full contact details.
