Databases and Google Scholar provide journal article and book citations in several citation formats including APA, MLA, and Chicago.
A quick way to find the citation for a journal article or book is to copy the article title or book title and then paste that information into Search Everything @ BU or Google Scholar, and then select the citing tool for that resources:
In 'Search Everything @ BU' first click on the article title and then on the Cite tool on right; select your format, like APA, and copy:
In 'Google Scholar' - click on the citation icon under the article abstract and then copy the citation in the desired format:
Both tools also offer an option to export to RefWorks or EndNote if you so desire.
Remember to ALWAYS proof-read citations for accuracy. The citations are machine-generated and are not perfect!
