6 Browsing still effective Journal browsing remains important for content discovery Users use journal browsing to abreast with subject area 31% of all full text article use on ScienceDirect is a results of journal browsing Users that start on a journal home page on average download 1.9 articles in a session User are provided the option to list favourite journals and receive Journal Issue alerts (Table of Contents)
