Practical Session

Much of the tutorial will be divided into 2 frames.
Left frame will hold the instructions for the tutorial. There are links to explanations which open in blue screens. Read the information on the blue screens, then close the blue screen to continue the tutorial.
Right frame opens into an OVID database screen, after clicking on the Database Link.

Ovid Logo is Ovid's new search interface which offers new ways of searching Medline, including Basic Search which uses Natural Language Searching and ranks results according to the frequency with which search terms appear in the results. For novice users and those who only require a few articles on their topic, Basic Search offers an easy but limited search method. For researchers and students doing literature reviews, and research requiring comprehensive coverage of the scholarly literature, Advanced Search is the optimal way to search using Ovid's powerful mapping feature which automatically maps to the nearest MeSH headings in Medline.
Advanced Search will be used exclusively in this tutorial.
