Public-domain opera libretti: where to find free texts and what copyright allows

Opera libretti were commonly printed for the audience of the first stage production³. As of 2000, the vast majority of the standard operatic repertory had reverted to the public domain, but the rules depend on the source, the country and the date³. This guide is part of the libretti section.

Where to find libretti at a glance

Wikisource

The Wikisource opera portal lists public-domain libretti of operas, operettas, oratorios and similar works⁴. Its external links include one titled 400 Librettos of the most famous Operas, as of the page checked 20 October 2026⁴. The list includes Aida, The Bartered Bride and HMS Pinafore, and also The Pirates of Penzance, Patience, Iolanthe, Princess Ida and individual selections from The Mikado⁴.

A single work shows how it is organized. The Wikisource page for Dido and Aeneas lists versions of the libretto by Nahum Tate, composed by Henry Purcell¹⁰. One version is the 1689 edition with libretto only¹⁰. Text on Wikisource is available under the Creative Commons Attribution-ShareAlike License¹⁰; on the portal, additional terms may apply⁴.

The site applies a licensing rule to every text. Wikisource requires every text to be in the public domain or under a compatible licence¹². A translation counts as a derivative work, and the contributor warrants that both the original and the translation are public domain or compatibly licensed¹². A translation has a copyright status separate from the original¹⁹. Original works on Wikisource, including translations, are licensed CC BY-SA unless stated otherwise¹².

IMSLP

The IMSLP librettos category holds publications of the text of operatic and vocal works that omit the music⁵. It listed 193 pages, checked 20 October 2026⁵, and it sorts by work type, instrumentation, composer and more⁵. Entries include Monteverdi’s L’Arianna, SV 291, Vivaldi’s Arsilda, regina di Ponto, RV 700, Hasse’s Achille in Sciro and Graun’s Armida, GraunWV B:I:23⁵.

librettidopera.it

For Italian opera, librettidopera.it is dedicated to Italian-language opera libretti⁶. Each libretto was searched for, copied and laid out with passion⁶. The site sets out to condense more than three centuries of libretto writing¹³ and lists libretti, MP3 pieces and images¹³. Its aim is popularizing rather than philological: to make known aspects of Italian culture¹³.

The title index gives the composer, the librettist and a date for each work⁶.

Il barbiere di Siviglia appears twice in the index: Paisiello’s opera of 1782 has a libretto by Petrosellini, Rossini’s of 1816 one by Sterbini⁶.

Project Gutenberg

The vast majority of Project Gutenberg’s eBooks are in the US public domain¹⁴. Its catalogue page counts 79,642 free eBooks, checked 20 October 2026⁸. Opera titles there include Kobbé’s Complete Opera Book, first published posthumously in 1919⁸, and Annesley’s Standard Operaglass, which gives plots and critical remarks for 151 famous operas²⁰. Kobbé’s page offers EPUB3, Kindle via Send-to-Kindle, plain text and older EPUB⁸.

Project Gutenberg’s permissions page puts the US limit plainly: outside the US, readers must confirm for themselves whether an item is free to redistribute where they are¹⁴. A copyright statement printed on an included title page does not mean the item is still copyrighted¹⁴. Gutenberg grants no permission for public-domain items, because nobody can¹⁴.

OperaFolio

OperaFolio’s libretti page contained 1051 links to the libretti, original and translated, of 512 operas, checked 20 October 2026¹⁵. The entries give the language of each text: Adam’s Le postillon de Lonjumeau (1836) with a French libretto and a German translation, Beethoven’s Fidelio (1805) with a German libretto plus English and Spanish translations, and Balfe’s The Bohemian Girl (1843) with an English libretto¹⁵. Modern entries sit in the same list: Bartók’s Bluebeard’s Castle (1918) with a Hungarian libretto and a Spanish translation, and Adams’s Nixon in China (1987) with an English libretto and a Spanish translation¹⁵.

Library of Congress catalogue

The Library of Congress published a catalogue of opera librettos printed before 1800 in Washington in 1914⁷. The scan shows no visible notice of copyright, with a stated date of 1914⁷. It has a title catalogue and a separate author list, composer list and aria index⁷. Oscar George Theodore Sonneck, Chief of the Division of Music, prepared it⁷.

The catalogue came from the Albert Schatz collection, which the Library of Congress purchased before planning the catalogue⁷. The collection held, in round figures, 12,240 librettos, not counting duplicates, of which 12,000 are opera libretti⁷. Schatz’s plan seems to have been to collect first editions, meaning librettos printed for an opera’s first performance⁷. He formed the collection over more than forty-two years of collecting, and his collection and other European librettos carried his history of opera to the point that the statistical part stood on about 80,000 cards⁷.

Harry Ransom Center and library guides

The Harry Ransom Center at the University of Texas at Austin holds 3,421 Italian opera libretti donated by the New York rare book dealer Hans P. Kraus in 1969¹⁶. The collection spans the 17th to the 20th century and includes cantatas, serenatas, oratorios, dialogues and Passions¹⁶. The Center’s page shows the title page of Peri and Rinuccini’s L’Euridice, Florence, 1600¹⁶, and the collection holds items published as early as 1600¹⁷. The items document performances by Italian, French, German and Austrian composers in numerous Italian cities¹⁶.

A 2010 review of the database counts over 3400 items, searchable by title, call number, librettist, location and printer¹⁷. The reviewer saw no digitized images; item pages give title-page information and the cast, if available¹⁷.

Opera Libretti is a selection of public-domain opera libretti and other vocal texts, and OperaGlass presents performance histories, synopses, libretti and discographies, according to the Eastern University library guide²¹. The guide also links the University of Illinois online scores at the Internet Archive as access to opera and vocal scores²¹.

OperaGlass

OperaGlass at Stanford lists libretti, source texts, performance histories, synopses and discographies for operas¹⁸. Its Wayback copy, checked 20 October 2026, indexes over 4800 opera composers with more than 25,000 operas and links to about 350 opera companies worldwide¹⁸. Its pages are marked as last maintained by Rick Bogart on 14 Feb 2020¹⁸.

What copyright still limits

In his 2000 survey, Lyle K. Neff of the University of Delaware called copyright law the most significant limit on the availability of libretti on the Internet³. Most of the standard repertory had reverted to the public domain, but many titles, especially recent ones, could not be posted without the copyright holder’s permission³. Copyright is also tied in with the availability of translations³.

Copyright term is the length of time copyright subsists before a work passes into the public domain⁹. It varies by jurisdiction⁹.

In the US, works first published in the US before 1931 are in the public domain through copyright expiration, and works first published abroad before 1931 are too, with a special case, on the Cornell chart²². In the US, works created but not published before 1 January 1978 may be protected until 2047¹. A work can be public domain in one country and protected in another¹¹.

The University of Montana chart covers literary, musical and dramatic works, and only works published or created in the United States²⁴. Under that chart’s rule of thumb, a work whose status cannot be determined is likely still covered by copyright²⁴.

Translations and editions

Wikipedia’s Public domain article states that translations or new formulations of public-domain works may be copyrighted in themselves, and that derivative works include translations, musical arrangements and dramatizations¹¹. In the US, per the Cornell guide, a copy of a public-domain work gains no new copyright, while a curated selection of public-domain works may have one²².

In the UK, per the University of Stirling guide, a typographical arrangement of a published edition has its own 25-year protection²³. When an author died fewer than 70 years ago and the estate or relatives cannot be contacted, the works are known as orphan works²³.

Neff noted that existing public-domain translations for much of the standard repertory could be put online, but they often contain out-of-date language or, if meant to be sung, do not render the meaning as accurately as a reading translation³. New translations are a rare occurrence online, because the volunteer nature of the enterprise limits contributions³.

A short history of the free-text web

Lyle Neff began a web page titled Public Domain Opera Libretti and Other Vocal Texts in 1995, relying on voluntary contributions of vocal texts and related information³. The first opera text he posted was Purcell’s Dido and Aeneas³, and contributions and links poured in quickly after the announcement³. He gave the paper at the ACRL Western European Studies Section Romance Languages Discussion Group annual meeting in Chicago on July 8, 2000³.

At that date there was a lack of anything comparable to the e-text repositories for opera libretti, oratorio texts and art song lyrics³. Libretti online came in formats from plain text to highly sophisticated HTML³. Italian, French and German items predominated³. Rick Bogart supplied many Italian operas and Robert Frone French opera³. A Don Giovanni literature site held eleven works in seven languages as of May 2000³. Eduardo Almagro’s site used borderless tables to show two parallel texts³.

Many early operas are known today only through the libretto, because the text was printed while the score stayed in manuscript and often disappeared or became fragmented³. An online libretto can also replace a lost booklet that came with a recording³.

Link rot was already a cost. A lost URL meant a lost libretto, and the Vox Neapolis site appears to have vanished, taking some dozen or so online libretti with it³. In a revision dated December 31, 2002, Neff recorded that his own site at Indiana University had been defunct since October 2002 and pointed readers to Rick Bogart’s OperaGlass³. He saw the need for at least an offline archive of the texts³.

Comparing a text with the vocal score revealed missing stage directions and the need to mark simultaneous singing³. The Indiana University Online Opera Scores Prototype held full public-domain vocal scores in facsimile³.

The 2000 survey also listed print series and specialist sites. Project Gutenberg and Athena were among the major repositories of publicly available online texts³. The series 101 Opera Libretti was published by Black Dog and Leventhal³, and each volume of L’avant-scène opéra carries a libretto with the original text and, where applicable, a parallel French translation³. A separate site carried sacred oratorio and cantata texts, mostly in German and Latin³. The space limits of projected titles generally allow only a condensation or sketch of what is sung³.

Using the texts

Each source states its own terms. Wikisource gives its license on the page: text is available under the Creative Commons Attribution-ShareAlike License¹⁰, and additional terms may apply on the portal⁴. A translation carries a copyright status separate from the original’s¹⁹, and copyright is tied in with the availability of translations³. The librettidopera.it index lists both the composer and the librettist beside each title⁶. Project Gutenberg’s permissions page says readers outside the US must confirm an item’s status where they are¹⁴.
