Although Presley had recorded a mammoth quantity of both released and unreleased material for RCA, the label didn't show much interest in repackaging it with the respect due such a pioneer. Haphazard collections of outtakes and live performances were far rarer than budget reissues and countless repackagings of the big hits. In the CD age, RCA finally began to treat the catalog with some of the reverence it deserved, at long last assembling a box set containing nearly all of the 1950s recordings. Similar, although less exciting, box sets were documenting the 1960s, the 1970s, and his soundtrack recordings. And exploitative reissues of Elvis material continue to appear constantly, often baited with one or two rare outtakes or alternates to entice the completists (of which there are many). In death, as in life, Presley continues to be one of RCA's most consistent earners. Fortunately, with a little discretion, a good Elvis library can be built with little duplication, sticking largely to the most highly recommended selections.
