Add another “knowledge-sharing resource” to your reference grab-bag: SciTopics, a free, searchable collection of over 600 science topic (hence Scitopics) pages, has just been officially lauched by Elsevier after a lengthy beta.
This is one of those resources that is excellent, if there happens to be an article on the topic you are looking for. Keep it handy, for it is likely it will help you (or your patrons/students) in the future.
