Google Scholar : Google for research
Wouter Gerritsma, February 2014
A few tips to use Google Scholar more efficiently
General Google syntax
Use ["phrase searching"]
Search for file type ["land degradation" ext:doc]
Search for specific domains ["land ownership" site:.ac.uk]
Search in titles [allintitle:anatomy plants water]
Search with OR ["carbon dioxide" OR CO2]
Exclude terms ["nutrient cycling" –nitrogen]
Combine ["carbon dioxide" OR co2 intitle:"nutrient cycles" -phosphorus ext:pdf site:.edu]
More tips:Google better with Google
What you can't do
Using numerical ranges
["Theobroma cacao" 2013...2014] Doesn't work in GS!
Use the year facet instead
Adjust the settings
Search results
●Number of results : 20 max
●Open in a new window
Languages
●Also in available in Dutch
Library links
●Choose link resolver of your University
Google Scholar advanced search
Google Scholar advanced search
Author search [author:"KE Giller"]
For journal searches you need the AS form
http://scholar.google.com/scholar?as_publication=%22agricultural%20systems%22
Searching for recent literature!
Use publication years
●In the advanced search
●Or use the facets in search result
Stemming, synonyms
Inclusion of word variants is unclear. (Google Scholar has a smaller dictionary than Google.com)
No verbatim search, but phrases do work! ["behaviour"]
Search explicitly for word variants still works [~behaviour]
Parentheses () do not work in Google (Scholar)!
Search engine results page (SERP)
Ranking influenced by citations (older articles on top!)
OA version
Save to My library
Reformat reference
Export to reference software
Other free versions(useful with cite)
Explore the subject
Alerts galore
For searching GS strings must be kept under 256 characters.
For alerts GS strings must be kept under 100 characters
My updates : Alerts based on the topics of your publications (my Citations)
My Citations & My Library
My Citations
●Your personal profile page, concentrating on publication lists and citations.
●Identifies you co-author network
My library
●Your saved articles
●Also lists all your references "cited by me"
●No plugin for word processors (yet)
Google Scholar quality
Coverage is still unclear
●Coverage is constantly growing, probably the most comprehensive scholarly literature database (Harzing,
2014. Scientometrics 98 (1): 565-575. http://dx.doi.org/10.1007/s11192-013-0975-y)
●Not all OA repositories are (fully) indexed (https://atmire.com/website/?q=content/google-scholar-and-dspace)
●Concentrates on scientific articles, share of books is growing, Grey Lit from repositories partially included
For systematic reviews Pubmed alone is sufficient, complementary searches in GS and other indexes are a necessity (Bramer, et al. 2013. Systematic Reviews 2 (1): 115. http://dx.doi.org/10.1186/2046-4053-2-115)
Metadata sometimes problematic, the version function under the snippet helps
Google Scholar and Google
Google and Google Scholar are separate indexes!
Google Scholar results are pushed in Google when searching for scientific subjects
●Make use of that reminder!
●But not the other way around
Some repositories are covered by Google but not in Google Scholar, or partly covered in Google Scholar
●Google Scholar [site:edepot.wur.nl]
●Google [site:edepot.wur.nl]
Thank you!
