Like other library platforms, CUNY OneSearch offers auto-citation generators, too. It is easy and fast. Its problem is apparent, too. Here is one example.
Problems with this auto-citation provided by OneSearch include:
Suggested citation in APA 6
Sales, N. (2018). American girls: Social media and the secret lives of teenagers. New York: Vintage Books.
Suggested citation in APA 7
Sales, N. (2018). American girls: Social media and the secret lives of teenagers. Vintage Books.
Note: APA 7 does not require the place of publication in the citation of books
Many databases, such as EBSCOhost, ProQuest, and JSTOR, offer the auto-citation feature. Once you find the record that you want in the database, you can click the "Cite" icon or the right half of the quotation mark ", which is generally used as a symbol representing auto-citation creation in the online environment. All you need to do is copy and paste it where needed. However, the disadvantage is that different editions of citation styles may not be clearly defined in some databases. You have to use your own judgment wisely; otherwise, systematic error could be generated when you simply do the copy-and-paste. (The above example is taken from EBSCOhost)
