The first stop for periodical article searching (including articles from academic peer-reviewed journals, magazines and newspapers) is the articles+ feature on the Princeton University Library homepage. articles+ searches many of Princeton's database subscriptions simultaneously, which has the advantage of federating multiple searches into a single search, and the potential disadvantage of often producing unmanageably large volumes of retrievals. Fortunately, the system provides a dashboard of filters and parameters which can be adjusted in order to winnow overwhelming lists consisting mostly of out-of-scope retrievals down to more compact lists with a much higher concentration of relevant material. Another strategy for targeting relevant material more narrowly is to be more selective at the database level. Below are links to databases grouped by discipline or subject matter. Many of these individual databases feature their own interfaces for strategically refining searches.
