In the narrow passageway of San Ginés, at its corner with Calle del Arenal and wall to wall with the church of San Ginés, is the oldest establishment in the passage, the San Ginés Bookstore. According to the academic Manuel Rico y Sinobas in his book “El Arte del Libro en España”, Diego Logroño is the first known bookseller, established there on November 29, 1650. A power of attorney is also preserved to sue against the Council of Castile, dated October 8, 1655, in which the signature of Andrea del Campo appears as the widow of Diego Logroño and established in the Puentecillo de San Ginés. The next clue to the evolution of the bookstore appears in 1767, in the book by Martín Cerecedo Ardid y Cano “El nuevo para todos”, in which he refers to the Post and Bookstore of Bartholomè López, next to the San Ginés Staircase. Gabriel Molina recovers it in his work "Libreros y editores de Madrid durante fifty años: 1874-1924", in which he indicates that in 1899 the bookstore was in the hands of Ángel and Manuel Calleja, who transferred it to Francisco Lastra and Anastasio Moya- No. In 1922 the owner is Antonio Sánchez, cited in the advertisement of the Espasa encyclopedia of that year as one of the establishments where one can find “The best dictionary in the world”. Luis Sanz, a bookseller of bookstore lineage, whose father ran a book stall on Calle de Santa Engracia, took charge of San Ginés in 1952. He has been in charge of the bookstore for more than 50 years, and his sons are now the establishment owners. Both continue to order the books daily in their old wooden shelves, so that both the regular customer and the occasional visitor admire this small and long-lived corner dedicated to books.
