[citation needed] In 2000, in collaboration with the ARTFL project at the University of Chicago,[5] the company began using semantic indexing techniques in its humanities databases.

It created metadata elements for gender, age, and sexual orientation of characters within plays; author nationality, birthplace and death place, as well as where and when an item was written.

[9][10] In November 2004, Alexander Street acquired the principal assets of Classical International,[11] a London and New York–based publisher of streaming music for libraries.

Using techniques such as semantic indexing, initially developed for textual databases, it was an early provider of synchronized, scrolling transcripts that allow the watcher to read ahead.

[citation needed] In June 2009 Alexander Street Press and Arcadia Publishing launched a research website to college local history information from around the United States and Canada.

[16] In 2013, the company launched a series of case study databases which combine books, audio, video, reports, pamphlets, and other primary sources.

These materials are made available using a wide range of business models, including demand driven (Access-to-Own, EBA, PDA), subscriptions, and perpetual licenses.
