Analysis of information sources in references of the Wikipedia article "Álbuns número um na Billboard 200 em 1967" in Portuguese language version.
In the history of the Billboard 200 chart, only three groups have reached No. 1 with their first four studio albums: One Direction, The Monkees (between 1966-1967) and The Kingston Trio (with their first five sets, 1958-1960). While all four of One Direction’s albums debuted at No. 1, The Monkees and The Kingston Trio’s releases climbed to No. 1 after entering the chart at a lower rank.
