Use advanced techniques in EconLit:
Search with the JEL subject classification system and the EconLit Thesaurus to identify subject terms.
Use the Index of Journal Titles in EconLit to perform a search for a particular journal
Use the History search in EconLit to combine the first two searches.
Browse the results for relevant review/survey articles.
When you search for articles, don't rely strictly on keyword searches.
Authors: After identifying important articles in your area, search for more articles by those authors.
Descriptors: Also, search in databases like EconLit for an article you've already read. Look at the descriptors used by the database to describe it. Perform new searches based on those descriptors.
Organizations: Organizations publish reports, too. If you identify a relevant organization, like the Mediamark (a company that surveys the public), for example, search for that organization as an author.
Advanced Search Screen: there are many options such as document type (case studies, book chapters, etc.), language or geographic limiters, NASIC codes, and so on.
