ii. Ask a Service
iii. E-mail
iv. Social Networking
Codes :
Answer: C
The medium for virtual reference progressed from e-mail, to the web form, to the ask-a service and then to social networking, which is the code iii, i, ii, iv.
Each step added a more interactive way of reaching the librarian. The other codes begin with social networking or the web form, which came after e-mail. Many questions asked in online reference now come through chat or social networks, while the early services used e-mail, so the order of progress follows the order in which the tools came into general use.
