Funded by the United States Department of Education, the ERIC (Education Resources Information Center) database has comprehensive coverage of education resources. It currently indexes over 1.6 million sources. Both journal and non-journal sources are available on the ERIC database. Journals indexed in ERIC are available here. A complete list of ERIC non-journal sources includes book published by the APA, TNTP research, reports funded by the Bill and Melinda Gates Foundation and a variety of state Department of Education documents.
The ERIC content/resources are searchable in three different interfaces. Each interface includes the same content, but they have different search features and they have full text of different sources. The three different platforms are:
The Thesaurus of ERIC Descriptors (aka ERIC Thesaurus) organizes ERIC sources by subject. When sources are grouped by subject it makes it easier to search for sources related to your research topic.
Within the Thesaurus are descriptors which are words or phrases that represent a subject. When a source such as a journal article is added to the ERIC database it is assigned descriptors.
A descriptor term entry page shows narrower terms (descriptors that are more precise), broader terms (descriptors that are less precise) etc. The following image is the page for the descriptor term "special education" :
