Are you using Knovel?
Knovel is a library search engine that allows you to search the full text of hundreds of electronic reference books focused on science and engineering.
If you're new to Knovel or even if you have used it in the past you may be interested to view the new tutorials they've put together on enhancing your Knovel experience. I went through the tutorials this morning and I learned new tricks and I've been using Knovel regularly for a couple of years.
You can either follow this link or look for the video camera icon the next time you're in Knovel.
