Like every April 23, we celebrate International Book Day. In Spain, as can be seen in multiple copies collected in the Catálogo Colectivo do Patrimonio, the day of the book was not always celebrated on April 23. King Alfonso XIII signed a Royal Decree on February 6, 1926, which officially created the Spanish Book Festival, to be held on the date that Cervantes was believed to have been born then, on October 7. The original idea was from the Valencian writer and editor Vicente Clavel Andrés, proposing it to the Cámara Oficial del Libro de Barcelona, where it was approved in March 1925, proposing that the entity be held in October of each year, on the date of Cervantes' birth.

Shortly after, in 1930, the date of April 23 was definitively established as Book Day, the day that Cervantes died. The celebration quickly took root throughout Spain, especially in the host cities of Universities, from Barcelona, it spread throughout Catalonia, although the official name was gradually diluted to coincide with the day of the patron saint, known as «Día de San Jorge» (Diada de Sant Jordi). In other non-university areas of Spain, the festival was of little importance or even disappeared, although it returned strongly from the 1980s, especially in Madrid. Over time, the exchange and gift of roses and books between couples and loved ones on that date became traditional in Catalonia, making it one of the most celebrated popular days.

In Spain, the annual delivery of the "Miguel de Cervantes" Spanish Literature Awards, the highest award given to Hispanic authors, is also celebrated on this date.

This tradition was one of the arguments used by UNESCO to declare April 23 "International Book Day". It was at the UNESCO General Conference, held in Paris in 1995, that it was decided to pay universal homage to books and authors on this date, encouraging everyone, and particularly young people, to discover the joy of reading and to value the irreplaceable contributions of those who have promoted the social and cultural progress of humanity, instituting for this purpose World Book and Copyright Day, as well as the UNESCO Prize for Children's and Youth Literature for Tolerance.

Galiciana joins the great book festival, highlighting the role of the first printers who came to Galicia, they were the pioneers of the Galician book. These first printers can be seen in a new and visual way through the Timeline that Galiciana offers on the microsite of the Catálogo Colectivo do Patrimonio de Galicia. Through this timeline we can consult, in addition to the places where they worked in Galicia through a map, a complete record of each printer, with links to their works and if they are digitized, access the digital copy, to observe the first printing jobs made in Galicia.

The first printer collected on the Timeline is Vasco Díaz Tanco, although a native of Fregenal de la Sierra (Badajoz), he established his printing press in Ourense where he printed in 1544, La carta q[ue] se mando poner al principio de las Constituciones Sinodales de Orense, whose original it is kept in the library of the Mosteiro de Poio and whose digital copy we can consult the full text in Galiciana.
