Oral history has become increasing popular in the past several decades, to the extent that it is practiced by school children as well as professional and experienced amateur historians.  You need, therefore, to be careful to determined who recorded the history and what practices and protocolls they observed. The source should make clear, for example, whether the account was tape recorded and transcribed or summarized based on notes. Was there one session or many.  Was the subject allowed to read or hear the account and correct errors? Was there one session or many?

I recommend Telling Stories : The Use of Personal Narratives in the Social Sciences and History / Mary Jo Maynes, Jennifer L. Pierce, and Barbara Laslett .Ithaca: Cornell University Press, 2008.  Chapter 5, "Making Arguments Based on Personal Narrative Sources," is particularly helpful.

The Oral History Association has adopted principles and policies for conducting oral histories (linked below), which you should be aware of.  I have also linked a review article that discusses five published oral histories.  It lays out many of the considerations that historians take into account when they are using such materials. The third link will take you to an online course on reading and litening to oral histories.  The summary in the middle section on "What to Ask" is particularly helpful.

Some collections of short stories have themes, but most are characterized by the subgenre (mystery, science fiction), the time or location of composition (19th century, Western states), or the identity of the author(s), who are usually described in the catalog by ethnicity, gender, national origin, or other distinguishing social characteristic.  Thus combining the phrase "short stories" with a suitable descriptor will usually find a collection of stories to choose from. For example, try "short stories latino" or "short stories lesbian"  or "short stories jewish".  You can also browse by subject, beginning your search with "short stories," and then either scroll until you find a narrower category of interest (e.g. Short stories, American--Michigan--Detroit) or just click on one or more of the broader categories and scroll until you a collection title catches your eye. We have hundreds of collections of stories to choose from.
