Today, most service organizations present their clients a series of communication modes, including text-based chat which affords including hyperlinks to pertinent information sources. No studies have yet examined how hyperlinks are employed in these interactions. Conversation analysis offers a range of concepts that can be used to examine the actions for which hyperlinks are being used. This paper explored the use of hyperlinks by professionals in two chat service types: 25 chat sessions from the Dutch national alcohol and drugs information service and 175 chats from an American university library chat service. Three types of hyperlinks were identified: (1) hyperlinks as direct replies to the client's inquiry; (2) hyperlinks as proposed answers with a subset of cases in which parties are navigating to the linked website; (3) and hyperlinks presented as supplemental resources. Supplying links can affect the service encounter by ending the chat when it represents an acceptable reply, by keeping the chat channel open when the client is not actively participating, or by launching a negotiation or collaborative navigation outside of the chat. Hyperlinking eases online service provision but may also imperil it when the link is treated as a proximate invitation.
