Library Orientation

I learned useful database in the ICU library such as GVRL and LexisNexis. I do not often go library but I realized that library is very useful for us. It is so useful for writing essay. We can search some topic which is written in newspaper or magazine in LexisNexis. In spring term, I had a hard time to search some evidence in newspaper or magazine and search for its WorkCited. I would like to use this  in next essay. What I thought the most useful database was Grammary. This will cheak our grammar in essay automatically. Also recommend us more proper words. I want to use library more efficiently!!!!
