1 Comprehensive Literature Searches using the Main Databases Rachel Couban Dec 4, 2014

3 Comprehensive Searching Techniques 1. Searching to inform a research ques<on Pearl- growing (also called snowballing, using one to find more) Scholarly communica<on techniques (reference lists and cita<on data) 2. Searching to answer a research ques<on Building Block approach Boolean logic operators Database tools

10 Pearl Growing Pearl growing uses the characteris<cs of a highly relevant and authorita<ve ar<cle, referred to as the "pearl," to search for addi<onal related sources. To use this technique, follow these steps: 1. Find a relevant and authorita<ve ar<cle 2. Locate and open the record for that ar<cle in a database 3. Review the subject terms that are used to describe and index the ar<cle in the database 4. Use the subject terms to search for further resources in the database by clicking on them if they are hyperlinked or including them as keywords in a new search statement If necessary, repeat the process as new sources are found URL: hkp://bowvalleycollege.libguides.com

11 Cited Reference Searching This method involves searching for sources that have cited a par<cular source in order to find similar and related materials as well as understand how an influen<al argument or research findings have been framed and discussed. Checking Reference lists ( Bibliographic Mining ) Bibliographic mining involves reviewing the reference list at the end of an book, journal ar<cle, disserta<on or similar work. The researcher then "mines" the reference list for further resources of interest and relevancy. hkp://bowvalleycollege.libguides.com/faculty

17 Building Block Strategy Building Block Strategy This simple and intui<ve approach involves breaking your research ques<on or informa<on need into dis<nct groups, or "blocks." Follow these steps: Iden<fy and divide main facets and concepts of the query into "blocks Using Boolean operators to account for synonyms or related terms, create a search statement for each block Test and evaluate your search statements Combine the search statements for each "block" into one query using "AND" hkp://bowvalleycollege.libguides.com/faculty
