What is an index and why should I care?
In essence, an index is a list of resources and where to find them, often with short descriptions of each resource. Indexes are good to use if you have already searched Dartmouth's collections and can't find enough material on your topic. Periodical indexes are also helpful if you have a general topic (e.g. vocal music of the 18th century, music in Ghana, conducting techniques) but aren't sure what the scholarly conversation around the topic is like. Using an index, you can find a journal on the general topic, read a few articles, and gain a quick understanding of what's going on in the field.
