A comparison of UNT Databases, Electronic Journals, eBooks, and our catalog items cannot be compared exactly to Google and Yahoo, because they have different system functions in a very different manner.
- UNT searches a well-defined set of items with clear specifications while Google's and Yahoo's scope of coverage is not defined; so we are not searching identical data.
- A direct comparison is impossible; however, we can look at the information possibilities between UNT's research options and Google and Yahoo.
UNT Research options:
- We use controlled vocabulary searching which includes a list of standardized subject headings to describe what a source is about. This allows researches the ability to identify more sources on similar topics with one search.
- A big problem many students struggle with his narrowing their topic.
- Developing a concise theses statement or question.
Google Scholar:
- Easy place to begin a search and find possible items.
- Can provide options for word usage in your searches.
- Can suggest a scholarly database or journal to look into.
- Does not offer the number and extent of special searching and limiting features.
- May find older items outside the parameters of some databases
- Can be difficult to find the actual article
- Possibly only the citation is available
- Possibly on the abstract is available
- May have access to gray literature (manifold document type) a document that is not controlled by a commercial publisher.
- Reports
- Conference proceedings
- Doctoral thesis/dissertations
- Blogs,etc.
Google:
- Overload of information - not necessarily on your specific topic.
- Quality of research information must be determined by your own evaluations
- Search content could be inundated with advertisements
- Searches all possible word variations
Yahoo:
- Overload of information - not necessarily on your specific topic.
- Quality of research information must be determined by your own evaluations
- Search content could be inundated with advertisements
