    An electronic database is a collection of records organized by some logical process. The information in the database is usually indexed and can be easily searched. Many electronic databases are available on-line, on a subscription basis.

    We subscribe to EBSCOhost, a database designed for high school students. This database provides full text for over 500 popular interest and current events periodicals. It also provides full text reference books, pamphlets, primary source documents, photos, maps and flags.


    We are a member of MLS (Massachusetts Library System). Membership in this multi-type library system gives us access to online reference databases, both in-library and from home.

    Citing Sources for Research Papers, Projects, and Assignments

There are many formats and styles to use in citing sources. Teachers will usually provide guidelines in the citation style they want you to use in their classes and help can also be found in the library. The following websites may be also be used to get help in the citation of sources:
