at the very least this will save time and it can stop you from making the same mistakes as othersto increase your breadth of knowledge of your subject area

Are the author's arguments supported by evidence (e.g. primary historical material, case studies, narratives, statistics, recent scientific findings)?Objectivity—Is the author's perspective even-handed or prejudicial? Is contrary data considered or is certain pertinent information ignored to prove the author's point?Persuasiveness—Which of the author's theses are most/least convincing?Value—Are the author's arguments and conclusions convincing? Does the work ultimately contribute in any significant way to an understanding of the subject?

Single Citation MatcherJournals Database. This database can be used to search for journals by journal title, Medline title abbreviation, or the International Standard Serial Number (ISSN). Clinical QueriesResults of searches on this page are limited to specific clinical research areas using automatic Research Methodology Filters.
PubMed has a total of more than twenty 20 citations and MEDLINE contains more than 17 million.OLDMEDLINE for pre-1966 citations. (~2 million citations as of 2010) Citations out-of-scope (e.g., covering plate tectonics or astrophysics) from some journals, primarily general science and general chemistry journals, for which the life sciences articles are indexed for MEDLINE In-process citations with records for articles before indexed with MeSH, added to MEDLINE or converted to out-of-scope status Citations that precede when a journal was selected for MEDLINE indexing (when supplied electronically by the publisher) Some life science journals that submit full text to PubMed Central and may not have been recommended for inclusion in MEDLINE although they have undergone a review by NLM, and some physics journals that were part of a prototype PubMed in the early 1990s

5. Display your citations Other options include:Summary (one line); Abstract (citation, abstract, and MeSH headings)MEDLINE (text format which includes field tags, used for importing into bibliographic management software like Reference Manager, RefWorks, or EndNote)Limits Part III B Searching in specific fieldsSelect limits that restrict your search results. Click on Limits above the PubMed query box to refine the search strategy to incorporate the language and year range. Your retrieval will still include all the PubMed in process records. IMPORTANT - If you add limits for any of the following: age group, publication type, human or animal, gender or subset you will eliminate retrieval of the PubMed in process records that are waiting for full MEDLINE indexing. Remember, the LIMITS you choose stay in effect for every search until you turn them off.2. Talk about the Boolean operators and make sure participants are comfortable with Boolean operators and stress need for operators to be in UPPER CASE Good example of need for upper case operatorsInfection and immunity VERSUS infection AND immunityThe first search yields all hits from the journal Infection and Immunity whereas the other maps to MESH terms and ‘text word’ searches as expected.

Objectives <br />To provide an overview of the steps involved with conducting a research literature review<br />To familiarize you with a variety of medical resources <br />
What is Literature Review?<br /> A literature review seeks to describe, summarize, evaluate, clarify and/or integrate the content of primary reports (research articles). It does not report new primary research itself. <br />Cooper, H. M. (1988) 'The structure of knowledge synthesis' Knowledge in Society, vol. 1, pp. 104-126<br />
to identify information and ideas that may be relevant to your project
to identify methods that could be relevant to your project</li></ul>To gain knowledge in the field<br />To identify other people who have the same interest as you do (a researcher network is a valuable resource)<br />You might be required to conduct one during your residency program <br />Bourner, T. (1996) 'The research process: four steps to success', in Greenfield, T. (ed), Research methods: guidance for postgraduates, Arnold, London. <br />
Types of literature review<br />Part of a work<br /><ul><li>Introduction section of a research article
Thesis and dissertations have also introduction section</li></ul>Stand alone <br /><ul><li>Review articles
Steps involved in conducting a Literature Review <br />Formulate your research question (define your scope and boundary)<br />Pick and prioritize your resource(s)<br />Develop a search strategy and conduct a literature search<br />Evaluate your results<br />Read the articles in-depth <br />Collect / Organize / Synthesis your results <br />Write your literature review<br />
Sample Search Question <br /> What is the efficiency of St. John's wort for smoking cessation? <br />
Keyword vs. MeSH Searching<br />Keyword Searching<br />Fast and easy<br />The results might be relevant or irrelevant <br />MeSH Searching<br />Can provide much needed precision<br />MeSH Retrieves Subjects – Not Words<br />
MeSH<br />Includes five types of terms <br /><ul><li>Headings
Grant Support </li></li></ul><li>MeSH Will NOT Help<br />If your topic is a new or emerging medical concept<br />If you suspect that very little has been published on your topic<br />If you want to retrieve recently published articles<br />Keywords are the only way in these situations<br />
St John Wort<br />SJW <br />Saint John's Wort<br />Smoking <br />Smoking cessation Tobacco use cessation <br />Nicotine withdrawal<br />
Sample Search Question <br /> What is the diagnostic utility of the urine biological tumor marker nmp22 (nuclear matrix protein 22) in detecting recurrence of bladder cancer?<br />Adapted from http://ebmlibrarian.wetpaint.com/page/Oncology/links<br />

Picking the right Database <br />Consider the following: <br />Subject coverage<br />Time span for coverage<br />Types of publications<br />Overlap in content with other resources<br />Frequency of update<br />How does the database work (index terms and other features) <br />

Google Scholar strengths<br />Easy to use, familiar search interface<br />Filters out the extensive popular sources found in a similar Google search<br />Searches full text<br />Easy cross-disciplinary searching<br />Provides access to full text via Library Links<br />"Cited by" allows for forward citation searching<br />
Google Scholar weaknesses<br />Not indexed articles <br />Fewer ways to limit and filter results than other research databases<br />Unknown coverage of research literature, possible gaps in coverage<br />No clear criteria of "scholarly" literature stated<br />Frequency of updates unclear, citations are not as current as citations in specialized databases such as PubMed<br />
