Guinness World Records - British Hit Singles & Albums is generally considered to be the authoritative reference source for both the UK Singles Chart (since its inception in 1952) and UK Albums Chart. It lists all the singles and albums ever to have made the UK Top 75 Charts in alphabetical order by both artist and song title, with date of chart entry, highest position, catalogue number, and number of weeks on the chart. Its sources are the New Musical Express chart from November 1952 to March 1960, and the Record Retailer (later Music Week) chart thereafter. Many observers have argued that this division is misleading, since the Record Retailer chart was little-known until it was adopted by the BBC in 1969, and that by adopting this chart as its standard from the earliest opportunity, the editors were effectively "re-writing" chart history. An example often given is the case of The Beatles' second single "Please Please Me" which was recognised as a number one hit by every other publicly-available chart but not by Record Retailer, and therefore not by British Hit Singles. Other records to which this applies include "19th Nervous Breakdown" by The Rolling Stones, "Stranger On The Shore" by Mister Acker Bilk and the Eurovision Song Contest entry "Are You Sure" by The Allisons. Co-founder Jo Rice has defended the book's choice of source material on the grounds that Record Retailer was the only chart to consistently publish a Top 50 from 1960 onwards (as opposed to other charts which published either a shorter listing, such as the NME, or a listing that shrunk over time, such as Melody Maker).
