The study also looks at reference question & answer delivery vehicles such as web forms, instant messaging, email, phone, Facebook, Twitter, Skype and more. The report also looks at the various costs of virtual reference – telecommunications, manpower, technology and equipment and at how libraries are using and safeguarding their reference response databases.
The study presents data from more than 50 academic, public and special libraries about their virtual reference systems. Data is broken out separately for these types of libraries, as well as by other criteria, such as the number of years that virtual reference has been in use, type of virtual reference service offered, and library size.
