A first approach to the vast bibliography of Pablo Neruda - and only the first editions in Spanish- confronts us with more than fifty books of verse and prose, which correspond to the first version of an extensive and wide work, which can be grouped into four categories:

a) Works published between 1923 and 1973.

Work published during the poet's life and includes, obviously, most of their titles.

b) Posthumous work, published in late 1973 and throughout 1974.

Corresponds to the seven books that Neruda wanted to celebrate its 70 years, and were almost finished at the time of the poet's death.

c) Dispersed Work, not collected in any book.

Corresponds to several volumes of verse and prose, originally published in brochures, magazines and newspapers.

d) Selected Epistolary.

This category would include the three books which collect important part of the correspondence of Neruda.

1. The letters sent between 1922 and 1932 to his great love of youth, Rosa Albertina Azócar.
2. A set of letters from the poet to his family, especially to Laura Reyes.
3. The volume that compiles the extensive correspondence that Neruda sends to his friend in Argentina Héctor Eandi.

This first global vision supports other bibliographical details, which are required for further examination of this issue.

There is no doubt that the prolific author of "Canto General" may have added several other individual books to his already vast production, if his interest had been - exactly - accumulate titles.

By contrast, he assimilated or incorporated a book perfectly individualized to another later publication, as occurred - for example - with "Spain in the heart" and "Alturas de Macchu Picchu". By orders of Neruda, "Spain in the Heart" (1937) will become part of "Third residence" (1947), while "Alturas de Macchu Picchu" (1947) find fair and accurate location in the "Canto General" (1950).
