1. What was discussed today in class?
Answer: Today in class we discussed about the haystac catalog and the call number.
2. Describe the differences between "words" and subject headings".
Answer: I think the difference between words and subject headings is that words is any word or phrase you think of that describes the topic to be searched and as for subject headings it is a specific word or phrase in a standard list of terms used to describe a topic.
3. What are the advantages and disadvantages of each of these search strategies?
Answer: The advantage of words is that you can use your own words to describe your topic and the advantage of subject headings is that all information retrieved will be relevant to the subject heading. And the disadvantage of words is that some information you retrieve will contain the keyword but the keyword may not meet what your topic is. And the disadvantage of subject heading is that sometimes there is no subject heading that exactly matches your topic. You may need to do a few searches using different subject headings to cover the topic.
