5. a)Do you have more or fewer entries with your subject heading search than with your keyword search?
- I have a fewer entries with my subject heading than with the key word search.

b)As you examine these results, are they more on target than the results you retrieved from your keyword search?
- Yes! With these results its exactly what I was aiming for instead of all these other results that were not relevant.

c)Why?
- I believe the reason why is because it once it eliminates all the other terms you don't need the type of subject you want to search for it will be narrowed down for you to choose from. I know this is a little complicated to understand i just believe that once i start with a subject and choose the kind of book it might fit into it, it can have other books that might make the searching easier to find!

{B} Describe the difference between a keyword search and a subject heading search:
-The difference between a keyword search and a subject heading search is basically the number of items it provides. In a keyword search there are more items presented that may be relevant to you search but not quite. In a subject heading search there is a major difference only because there are less items and more efficient related items to choose from. It is closer related to your subject.
