Librarians are now conducting instruction for distance learning students beyond their traditional work. Technology advancements have enhanced the delivery mode in distance learning across academic disciplines. Online conference tools originally designed for commercial use are now Web-based conferencing tools allowing librarians to be innovative in their service delivery, disregarding proximity barriers. This article talks about selection criteria and important features to consider when selecting e-learning instruction software. Suggestions of some free Web-based conferencing tools are provided.
