Although research has examined nonprofit organizations' use of information and communication technologies (ICTs), particularly social media and websites, we know little about how nonprofit organizations use ICTs in the context of interorganizational collaboration. This article reports the results of an exploratory study on how nonprofit organizations use ICTs for collaboration, drawing from a random sample of human services nonprofit organizations in the United States. The results show that email, teleconference, and shared repositories were the preferred ICTs more than case management software and databases. ICTs were used for coordination, information sharing, relational communication, and client management. In addition, ICT use and utilities vary in different types of collaboration. Further, operational capacity, percentage of government funding, overall ICT capacity, and organizational size influenced the patterns of ICT use in nonprofit collaboration. We draw from our findings to suggest implications for the study of nonprofit collaboration and ICT use.
