Opac Search Tips 2009

  1. 1. CHOOSE THE BEST SEARCH STRATEGY <ul><li>title search:- you must know the first words of the title </li></ul><ul><li>author search: - you must know author’s last name </li></ul><ul><li>subject search: - if you have a specific term - if you want to see the alphabetical subject index </li></ul>
  2. 2. A KEYWORD IS….. <ul><li>a significant word used in indexing </li></ul><ul><li>A significant word from a title or document </li></ul><ul><li>An unusual word, a less common word, a specific word, an author’s first name….. </li></ul>
  3. 3. KEYWORD SEARCHES: <ul><li>perform broad, general searches in databases and search engines </li></ul><ul><li>have the potential to find large amounts of unrelated information or sites </li></ul><ul><li>should use specific or unique terms to avoid information overload! </li></ul>
  4. 4. KEYWORD SEARCHING THE LIBRARY CATALOG (“OPAC”) <ul><li>looks in four places on every record: </li></ul><ul><ul><li>Title index </li></ul></ul><ul><ul><li>Author index </li></ul></ul><ul><ul><li>Subject indexes </li></ul></ul><ul><ul><li>Notes field of the catalog record </li></ul></ul><ul><li>is usually the default search if you choose the “enter” key </li></ul>
  5. 5. Beyond the Basics <ul><li>“ Power” / “Advanced” / “Boolean” searches are powerful keyword searches which are available in all electronic databases </li></ul><ul><li>Search terms are combined by using specific “operators” – AND, OR and NOT – to streamline results </li></ul><ul><li>AND - all terms must be in the record </li></ul><ul><li>OR - any of the search terms are acceptable </li></ul><ul><li>NOT - only some of the terms are acceptable </li></ul>
  6. 6. Sample Searches <ul><li>POWER icon is the library catalog option </li></ul><ul><li>Each operator will give a very different result for the same search </li></ul><ul><li>Atwood AND criticism -> 15 hits </li></ul><ul><ul><li>Results have both words on every record </li></ul></ul><ul><li>Atwood OR criticism -> 571 hits </li></ul><ul><ul><li>Results have at least one of these two words on every record </li></ul></ul><ul><li>Atwood NOT criticism -> 30 hits </li></ul><ul><ul><li>All results contain the word Atwood; none have the word criticism </li></ul></ul>
  7. 7. TROUBLESHOOTING <ul><li>TRY CHECKING YOUR SPELLING </li></ul><ul><li>try a synonym for your original term </li></ul><ul><li>try a more general term or a more specific term </li></ul><ul><li>try using only one or two words for your search </li></ul>
  8. 8. CALL NUMBERS: the mystery! <ul><li>A call number is simply a combination </li></ul><ul><li>of numbers and / or letters that </li></ul><ul><li>describe where to find a resource in a </li></ul><ul><li>library. </li></ul>
  9. 9. CALL NUMBERS USE A COMBINATION OF : <ul><li>LOCATION CODES </li></ul><ul><li>DEWEY DECIMAL NUMBERS </li></ul><ul><li>AUTHOR / TITLE CODES </li></ul>
  10. 10. Reference and Non-fiction <ul><li>Are classified using the Dewey Decimal system, so </li></ul><ul><li>they always have a number code and author or title code </li></ul><ul><li>Reference books have REF or REF SET as a location code (the reference section is located in the middle of the library by the window) </li></ul><ul><li>Non-fiction is located on the tall shelves at the back of the library </li></ul><ul><li>For instance: </li></ul><ul><ul><li>Non-fiction call number: </li></ul></ul><ul><ul><ul><li>909.82 JAN </li></ul></ul></ul><ul><ul><li>Reference call number: </li></ul></ul><ul><ul><ul><li>REF 909.82 JAN </li></ul></ul></ul>
  11. 11. Fiction <ul><li>Fiction is not classified by Dewey Decimal </li></ul><ul><li>numbers, so does not have a number code. </li></ul><ul><li>Fiction is alphabetized by author’s last name. </li></ul><ul><li>Fiction material is found in the back left hand corner of the library. Check out the new fiction on the table by the circulation desk. </li></ul>
  12. 12. Fiction call numbers <ul><li>FIC + author code </li></ul><ul><li>Fully alphabatized </li></ul><ul><li>SC + author code </li></ul><ul><ul><li>Anthology collection </li></ul></ul>
  13. 13. Other odd location codes <ul><li>ENG </li></ul><ul><li>SOC </li></ul><ul><li>SOC AP </li></ul><ul><li>VHS </li></ul><ul><li>DVD </li></ul><ul><li>Sorry! Any material with these location codes is for teacher use only. </li></ul>
