Library Skill Modules

I think the Library Skill Modules are a very helpful and useful tool when it comes to using the library. Half the time when I search for something I just type in the first thing that comes to mind and pay no attention to whether it is too narrow or too big. I also never considered that this could effect my search results. Another thing I never knew was that library's search for the literal term and you can us truncation to find different tenses of the word you searched. I always try to think of synonyms but I never realized that just expanding the words you use and putting the word "and" and "or" can help find better articles/books that related more to the topic your looking for.
