"A hugely popular website for theatre fans, Broadway.Com is a great place for news and features on all the currently running Broadway fare."
"...is the main website of The Broadway League, which is the national trade association for the Broadway industry. It’s basically a big group of all the theatre owners and such from all across the country. It’s a great source of information on Broadway and touring shows as well as events such as Kids Night on Broadway."
''Another amazing source of Broadway breaking news, Broadway World is great not only for NYC news and features, but for all cities across the country. "
Did He Like It?
"A website with a great and surprisingly novel idea, Did He Like It? curates all the different major reviews for Broadway and Off-Broadway shows and answers the question,'Did he (or she) like it?'"
Internet Broadway Database (IBDB)
"An absolutely essential site for theatre lovers, the Internet Broadway Database (IBDB) has listings for every Broadway show that ever happened. Want to know who was in the original production of Porgy and Bess in 1935 or who replaced Patti Lupone in Evita? IBDB is the place to find out."
Lucille Lortel Foundation
"Besides offering excellent information on the foundation’s work and lots of history of the Lucille Lortel Theatre, one of Off-Broadway’s best theatres, this website contains the Internet Off-Broadway Database (IOBDB)."
"A great site to visit for breaking theatre news and show information, Playbill is a trusted source of news for the theatre community."
"A great new website, Show-Score is kind of like Yelp, but for theatre. Browse all the shows to see how actual theatre-going people feel about the shows playing in New York and beyond."
"...is a site with many different facets. Probably best known as the home of the 'All That Chat' message boards, Talkin’ Broadway also features a weekly roundup of all the soon-to-be-released CDs, books and DVDs, and a Shoppin’ Broadway board where users post tickets, memorabilia and other theatre-related things for sale."
Theatre Library Association (TLA)
"Founded in 1937, the Theatre Library Association supports librarians and archivists affiliated with theatre, dance, performance studies, popular entertainment, motion picture and broadcasting collections. TLA promotes professional best practices in acquisition, organization, access and preservation of performing arts resources in libraries, archives, museums, private collections, and the digital environment. By producing publications, conferences, panels, and public events, TLA fosters creative and ethical use of performing arts materials to enhance research, live performance, and scholarly communication."
"...is one of the best sites out there for theatre nerds! Besides inspiring (and often hilarious) memes featured on the site and on the TheatreNerds Facebook page and an incredible Swag Shop, a new article every day makes it an essential website to visit daily."
