Sometimes you get what you pay for, but even then it's wise to check carefully. CPDL depends on volunteerism, and might benefit from a proofreading-rating: in the meantime you can help improve things by adding to the Edition notes: the code {{ScoreError|details}} or {{ScoreError|see list of errata on talk}}. Or even adding something like this.I strongly recommend using a purchased edition for the parts rather than the online one off CPDL. There are so many mistakes in that edition that it takes almost as much time to fix everything there as it would take to make one’s own edition!
