As of yesterday, Monday, August 9, there have been problems with finding full text articles in the ATLA Religion Database. EBSCO recently released a new upgrade to their search interface, and evidently something has happened to the ability to limit searches to only full text articles, particularly in the ATLA Religion Database.
Until EBSCO can resolve this problem, please be aware that if you are using the ATLA Religion Database and want to find only full text articles, using the "Full Text" check box to limit your results to only full text will most likely cause you to retrieve only some of the full text articles.
The best way to ensure that you are finding all full text articles is to not use any limit on the search and then manually sort through the results.
I will post an update once EBSCO confirms that they have resolved this problem.
