Besides the albums such as those by the Miracles, Supremes, and Temptations noted previously, consisting of a mix of previously-released singles and unreleased tracks, the other kind of problematic release when defining compilations is the boxed set combining "hits" and other previously-released tracks (singles or album tracks) with out-takes, alternate versions, and other rarities. Two examples come from the Yes discography: Yesyears, and its successor, In a Word: Yes (1969- ). Both consist mostly of previously-released tracks, but they also both feature a selection of previously-unreleased material. A boxed set with the balance skewed more towards previously-unavailable material is the first volume of Neil Young's Archives. But, to find a boxed set that arguably warrants status as a minor album instead of a compilation, we turn to Jefferson Airplane Loves You. Twenty-three of its 52 tracks were previously unreleased; however, many of those 23 tracks are concert recordings. As with the difficult case of albums with a mix of studio and concert tracks, boxed sets suggest that perhaps the minor-album category should be broader, including releases with such mixed assortments. In this scenario, Yes's Keys to Ascension albums, Young's Archives sets, those Motown albums (Where Did Our Love Go, The Temptin' Temptations, Going to a Go-Go), and Jefferson Airplane Loves You would also fall into that category; precisely because doing so lets the reader know not to dismiss them as concert albums or compilations, while still noting that they are not major studio albums consisting mostly of original material.
