Citation database of scholarly articles spanning the sciences, social sciences, arts, and humanities. Indexing goes back to 1900. This database can also search for articles that cite a particular work or author. Formerly called Web of Knowledge.
What is a subject specific database?
Subject-specific databases are like boutique stores. They specialize in a specific subject area and tend to include scholarly journals, book chapters, and dissertations. Databases in certain fields such as business, may also include trade journals.
Do they overlap with the general databases?
While there may be some overlap, subject-specific databases index the core journals for that area and provide more depth of coverage as compared to a general database.
