Good idea to recycle archive articles in ebook form, at an impulse-buy price, but the execution is a bit poor. Being Guardian articles it's hard to know of some of the typos have been left in from the original editions or introduced in the conversion process. A piece about McCartney's birthday was incorrectly dated July 18th (should be June), which, given there were also references to the Olympics and the Diamond Jubilee is liable to confuse.
Given the articles are all from the Guardian, there is nothing like the range of Mike Evans's "Paperback Writer" anthology. Some of the articles chosen are quite slight, but there are enough meaty ones to make it worth the small price of entry, and it's an interesting enough addition to the standard accounts of the Beatle chronology. But the Evans book is still probably better value .The Beatles Paperback Writer: 40 Years of Classic Writing
