Input: Question: How many total albums have the Swedish pop group ABBA released? Passage 1:Included in the BPL's research collection are more than 1.7 million rare books and manuscripts. It possesses wide-ranging and important holdings, including medieval manuscripts and incunabula, early editions of William Shakespeare (among which are a number of Shakespeare quartos and the First Folio), the George Ticknor collection of Spanish literature, a major collection of Daniel Defoe, records of colonial Boston, the 3,800 volume personal library of John Adams, the mathematical and astronomical library of Nathaniel Bowditch, important manuscript archives on abolitionism, including the papers of William Lloyd Garrison, and a major collection of materials on the Sacco and Vanzetti case. There are large collections of prints, photographs, postcards, and maps. The library, for example, holds one of the major collections of watercolors and drawings by Thomas Rowlandson. The library has a special strength in music, and holds the archives of the Handel and Haydn Society, scores from the estate of Serge Koussevitzky, and the papers of the important American composer Walter Piston.
 Passage 2:In 1962, when only 14, he was fascinated by the success of the Arab national and anti-colonial forces that defeated the French colonial armies in the Algerian War, gaining independence for their country. When attending a military college in Kętrzyn (Ger. Rastenburg) in 1966-1969, he actively opposed the Polish communist regime during the 1968 Polish political crisis, and as a result was expelled from the Officer School, and became a political prisoner for the first time. He continued his studies at the University of Silesia in Katowice, and after graduation was employed there as a lecturer,adiunct and researcher. In 1980-81, when Poland was swept by a wave of anti-communist strikes, and around ten million joined the anti-communist Solidarity trade union, Kopański co-founded a branch of this broad grassroots social movement at the University of Silesia.
 Passage 3:The Definitive Collection is a 2001 compilation album of all the singles released by Swedish pop group ABBA. It consisted of two discs: the first featuring the singles from 1972–79 ("People Need Love" to "Does Your Mother Know"), and the second including the singles from 1979–82 ("Voulez-Vous" to "Under Attack"), with the tracks being listed in chronological order. The main exception is the track "Thank You for the Music", which, despite being written and recorded in 1977, was in fact released as a single (primarily in the UK) in 1983 after the band had split up. It appears on disc two, along with two bonus tracks, "Ring Ring" (1974 UK single remix), and "Voulez-Vous" (1979 US promo extended remix). The Australian version of The Definitive Collection adds a further two bonus tracks: "Rock Me" and "Hasta Mañana". The 1974 remix of "Ring Ring" is the first appearance on CD of this version mastered from the original master tape, after the UK single master tapes had been returned to Polar Music by the former UK licensees, Epic Records. The track's previous appearance on CD, in a 1999 singles boxed set, was mastered from a vinyl single.
