Scholarly work is often published as journal articles, which you can find by searching in various databases. Each database allows you to search a particular set of scholarly journals. You will want to cast your net wide at first, trying various search words (keywords) and browsing through the results in each database.
Many of the questions considered in the Seminary cross academic disciplines. Because of this, it can be useful to utilize interdisciplinary databases and search tools.
These topic-specific databases cover religious studies and biblical scholarship at different levels, from overviews to peer-reviewed articles. Many offer additional tools for searching, like ATLA's Scripture Citation Index and Thesaurus, both of which can help you perform targeting searches for very specific topics. Be sure to read through the descriptions to see which of these might be most useful in your research.
