You may want to consider using a library database instead … What is a library database?
A website that requires a paid subscription in order to access information. Contains information from published works such as articles from magazines or encyclopedias. Can be used to search for titles, authors, magazines, dates, etc. Often give you access to full-text articles that can be printed or e-mailed. Are selected by librarians to meet the needs of their library patrons.
How is a library database different from a website? Library Databases Get their information from professionals or experts in the field. Contain published works where facts are checked. Easy to cite in a bibliography and may create the citation for you Help you narrow down your topic or suggest related subjects. Updated frequently and include the date of publication. Available to anyone using a computer in a library that subscribes to databases or any library cardholder using a computer outside the library. Websites Can be written by anyone regardless of expertise. Content is not necessarily checked by anyone, expert or not. Don't provide the information necessary to create a complete citation. Aren't often organized to support student research needs. May not contain current information or indicate when a page is updated. Available to anyone with an internet connection inside or outside the library.
