"Up until the early 2000s, libraries probably had only one catalog, hosted by an integrated library system. By 2011, most libraries had more than one catalog featured on their library website. There are many third-party information systems that work with library catalogs. Many library catalog interfaces are also powered by enhancement tools such as Encore, VuFind, or LibraryThing."

"Why all the fuss over tweets? Twitter hosts valuable, communal conversation in real-time. And Twitter trends become more powerful the more users contribute to the dialogue. Finally, Twitter allows the chatter of millions to be parsed into channels (hashtags) of real-time conversation that covers widely varying topics. Jokes, rumors, political movements, pop culture fanaticisms, the collective screaming of teenagers — they all bubble to the surface and shift and change like an oil slick, much like a collective human consciousness."
