  1. 1. Finding Information in the Biological Sciences Bruce Slutsky Robert Van Houten Library
  2. 2. The Scientific Method <ul><li>The scientific method is the process by which scientists, collectively and over time, endeavor to construct an accurate representation of the world.  There are various thought processes that are used when the scientific method is employed </li></ul>
  3. 3. Information Retrieval <ul><li>Scientists, engineers and students must be able to find information at all levels from a multitude of information resources available to them. </li></ul>
  4. 4. Similarities between the Scientific Method and Information Retrieval <ul><li>Scientific Method </li></ul><ul><li>Know the subject </li></ul><ul><li>Require new knowledge </li></ul><ul><li>Propose an experiment to find new knowledge </li></ul><ul><li>Conduct the experiment </li></ul><ul><li>Observe and interpret the results </li></ul><ul><li>Revise the experiment </li></ul><ul><li>Interpret the final outcome of the experiment </li></ul><ul><li>Information Retrieval </li></ul><ul><li>Know the scope of and contents of databases in his/her field of endeavor </li></ul><ul><li>Require new knowledge </li></ul><ul><li>Devise an initial search strategy using relevant terminology in subject databases </li></ul><ul><li>Examine the initial answer set </li></ul><ul><li>Revise the strategy based on findings from the initial answer set </li></ul><ul><li>Explore alternative search options </li></ul><ul><li>Examine the final answer set </li></ul><ul><li>Find the relevant documents </li></ul><ul><li>Use the information found </li></ul>

  18. 18. Flow of Scientific Information <ul><li>Scientists and engineers conceive ideas and perform experiments in the laboratory.  They want to make the results of their research public.  </li></ul><ul><li>The published information flows from the top of the chart (next slide)to the bottom.  Students needing information must start their research at the bottom of the chart.  Tertiary literature such as handbooks, encyclopedias, and textbooks should be consulted first </li></ul>
  19. 19. Flow of Scientific Information
  20. 20. Types of Databases <ul><li>Bibliographic - includes the elements needed to identify the document </li></ul><ul><ul><li>Author(s) </li></ul></ul><ul><ul><li>Title </li></ul></ul><ul><ul><li>Journal, Year, Volume, Issue Number, Pages </li></ul></ul><ul><li>Abstract - a one paragraph summary of the article to help the researcher decide if it is relevant to the research question </li></ul><ul><li>Full-Text - includes the entire article in electronic format </li></ul>
  21. 21. Database Formats <ul><li>Print </li></ul><ul><li>Very cumbersome and difficult to use </li></ul><ul><li>Online (1970s to the present) CD-ROM (1980s to the present) - Only so much information can fit on one disk </li></ul><ul><li>World Wide Web (1990s to the present ) </li></ul>
  22. 22.

  25. 25. Databases with Biology Content from the NJIT Library <ul><li>BioMed Central </li></ul><ul><li>BioOne </li></ul><ul><li>Medline (PubMed) </li></ul><ul><li>Pubget </li></ul><ul><li>Scopus </li></ul>
  26. 26. BioMedCentral <ul><li>Publisher of 208 peer-reviewed open access journals </li></ul>
  27. 27. BioOne <ul><li>BioOne provides a unique aggregation of high-impact bioscience research journals, featuring timely content on a wide-array of today’s most pressing topics. </li></ul><ul><li>You may search this database for free, but will have to go to Rutgers to get the full-text of articles. </li></ul>
  28. 28. Medline <ul><li>MEDLINE is the NLM's (National Library of Medicine) premier bibliographic database covering the fields of medicine, nursing, dentistry, veterinary medicine, the health care system, and the preclinical sciences. MEDLINE contains bibliographic citations and author abstracts from more than 4,800 biomedical journals published in the United States and 70 other countries. The database contains over 12 million citations dating back to the mid-1960's. The Pubmed version is free. </li></ul>
  29. 29. Pubget <ul><li>Pubget is a search engine for PDFs in the life sciences. It indexes nearly 20 million life science research documents, including those in PubMed®. You search it like you would PubMed or Google Scholar. The difference is Pubget gets you the PDF right away . </li></ul>
  30. 30. Scopus <ul><li>Scopus is a multidisciplinary navigational tool that contains records going back to the mid 1960s, offering newly-linked citations across the widest body of scientific abstracts available in one place.  Biology is one of the many subjects covered in Scopus </li></ul>
  31. 31. Boolean Logic <ul><li>AND </li></ul><ul><li>The Boolean AND narrows your search by retrieving only documents that contain every one of the keywords that you enter.  The more terms you enter, the narrower your search becomes.      EXAMPLE: insecticide AND cockroach </li></ul><ul><li>     EXAMPLE: insecticide AND cockroach AND toxicity and children </li></ul><ul><li>OR </li></ul><ul><li>The Boolean OR expands your search by returning documents in which either or both keywords appear.  The more keywords you enter, the more documents you retrieve.    EXAMPLE: pesticides OR insecticides </li></ul><ul><li>   EXAMPLE: pesticides OR insecticides OR herbicides </li></ul><ul><li>NOT </li></ul><ul><li>The Boolean NOT limits your search by returning only the first keyword but not the second, even if the first word appears in that document, too    EXAMPLE herbicide NOT insecticide    EXAMPLE insecticide NOT rodenticide </li></ul><ul><li>To do an effective search you must choose the most relevant database(s) and the appropriate Boolean Logic </li></ul>
  32. 32. Availability of Journals <ul><li>Once you do a search, you must locate the articles that you retrieved from the search that you think are relevant.  They may be available: </li></ul><ul><li>Print only </li></ul><ul><li>Electronic Only </li></ul><ul><li>Print and Electronic </li></ul><ul><ul><li>Dates of electronic availability vary </li></ul></ul><ul><li>Not available at NJIT - order through interlibrary loan </li></ul>
  33. 33. Devising Optimal Search Strategies <ul><li>Choose the proper database(s) </li></ul><ul><ul><li>Be aware of the scope and limitations </li></ul></ul><ul><li>Use all relevant search terms and appropriate Boolean logic </li></ul><ul><ul><li>Think of concepts not words </li></ul></ul><ul><li>Devise a search strategy for: </li></ul><ul><ul><li>Precise search </li></ul></ul><ul><ul><ul><li>Expand strategy if too few are found </li></ul></ul></ul><ul><ul><li>Exhaustive search </li></ul></ul><ul><ul><ul><li>Cut down if too many citations are retrieved </li></ul></ul></ul>
  34. 34. Evaluating References <ul><li>Look at the abstract to judge if the paper is relevant to your topic </li></ul><ul><li>If so, is the paper available from the NJIT Library? </li></ul><ul><li>Follow links in the database that you used to check for availability of the article. </li></ul>
