Shakespeare's sonnets
The primary source of Shakespeare’s sonnets is a quarto published in 1609 titled "Shakespeare’s Sonnets." It contains 154 sonnets, which are followed by the long poem "A Lover's Complaint". Thirteen copies of the quarto have survived in fairly good shape from the 1609 edition, which is the only edition; there were no other printings. There is evidence in a note on the title page of one of the extant copies that the great Elizabethan actor Edward Alleyn bought a copy in June 1609 for one shilling.
Shakespeare's sonnets
Apart from rhyme, and considering only the arrangement of ideas, and the placement of the volta, a number of sonnets maintain the two-part organization of the Italian sonnet. In that case the term "octave" and "sestet" are commonly used to refer to the sonnet’s first eight lines followed by the remaining six lines. There are other line-groupings as well, as Shakespeare finds inventive ways with the content of the fourteen line poems.
