Overview
Ephemera - Associação Cultural is a Portuguese non-profit cultural association dedicated to the preservation, study and public dissemination of the library and archive assembled by José Pacheco Pereira, a prominent Portuguese professor, contemporary-history researcher, journalist, columnist and politician. The project began in 2003 in the village of Marmeleira (municipality of Rio Maior) and grew into one of the largest private libraries in Portugal, holding more than 200,000 titles. In 2009 it was formally constituted as the Ephemera Biblioteca e Arquivo de José Pacheco Pereira, and in April 2017 a cultural association was created around the library with 20 founding members, later counting more than 120 associates. The association's logo is inspired by a clock held in the archive, a symbol of the passage of time, designed by Henrique Cayatte. The collection is generalist in scope but strongly specialised in contemporary social, cultural and political history, with archival materials and collections that are unique in Portugal in certain areas. It includes documents, materials and objects linked to the social and political activism of its founder, such as the papers of Francisco Sá Carneiro and the furniture of Vítor Crespo, President of the Portuguese Assembly of the Republic between 1987 and 1991. Over the years the archive has received numerous bequests and donations, ranging from simple collections of political stickers to nationally significant estates such as those of Francisco Sá Carneiro, José Fonseca e Costa, Nuno Rodrigues dos Santos, Vítor Crespo, Carlos da Fonseca, José Carlos Ferreira de Almeida, Rodrigo Sousa e Castro and Francisco Ferreira ('Chico da CUF'). Ephemera operates from several locations: Marmeleira, Lisbon and Barreiro, with collection points in Viana do Castelo, Porto, Lamego, Guarda, Figueira da Foz, Coimbra, Santarém and Torres Vedras. In Marmeleira, by the end of 2018, the archive occupied six contiguous buildings housing more than 200,000 books and countless magazines, newspapers, pamphlets, pins, stickers, posters and other objects. In March 2016 a work and reception space was opened on the first floor of the Ler Devagar bookshop in the Lx Factory in Lisbon, and in December 2017 a 400 m² warehouse was established in the Barreiro business park, in the former CUF/Quimigal facilities. A partnership with Baía do Tejo, agreed in April 2018, provides for regular cultural initiatives open to the community. The association has been recognised publicly: on 22 February 2020 it was made an Honorary Member of the Order of Merit. It is also described as 'the most public private archive in Portugal'. In September 2017, TVI24 began a regular collaboration with the Associação Cultural Ephemera and José Pacheco Pereira, broadcasting a weekly programme by the author to make the archive known under the motto 'preserving the memory of the past as an instrument of democracy in the present'. The programme ran for several seasons. The association continues to pursue its statutory aims: promoting and sponsoring the preservation of cultural, historical, scientific and educational heritage, developing research and study in history, sociology and literature, and organising and maintaining the archive and library of José Pacheco Pereira and all others incorporated by purchase or donation.
History
Ephemera originated as a private collection assembled by José Pacheco Pereira, whose first personal acquisitions date from 1963. The project to make the library and archive public began in 2003 in the village of Marmeleira, municipality of Rio Maior, where Pacheco Pereira acquired a house to reunite his library. The original private holdings came from three main sources: the library and papers of the Pacheco Pereira family, largely held by Álvaro Pacheco Pereira (died 2012), and the library and archive of José Pacheco Pereira himself. Over time, the collection was expanded by donations, bequests and purchases, growing into one of the largest private libraries in Portugal with more than 200,000 titles. In 2009 the project was formally constituted as the Ephemera Biblioteca e Arquivo de José Pacheco Pereira. In March 2016, Ephemera opened a work and reception space on the first floor of the Ler Devagar bookshop in the Lx Factory in Lisbon, one of the city's most emblematic cultural venues, where volunteers collect and process numerous collections. In December 2017, the archive acquired a 400 m² warehouse in the Barreiro business park, in the former CUF/Quimigal facilities, creating an important base for processing larger collections and estates. In April 2018, a partnership was established with Baía do Tejo providing for regular cultural initiatives open to the community. In April 2017, the Associação Cultural Ephemera (ACE) was constituted by 20 founding members, with a mandate for 2017/2019. The association is a non-profit cultural body whose statutory purpose is to promote and sponsor the preservation of cultural, historical, scientific and educational heritage, to develop research and study in history, sociology and literature, and to organise and maintain the archive and library of José Pacheco Pereira and all others incorporated by purchase or donation. By the end of 2018, the archive in Marmeleira occupied six contiguous buildings housing more than 200,000 books and a vast quantity of periodicals, pamphlets, pins, stickers, posters and other objects. The association has more than 120 associates, and the possibility of transforming it into a foundation has been studied. In September 2017, TVI24 began a regular collaboration with the Associação Cultural Ephemera and José Pacheco Pereira, broadcasting a weekly programme by the author to publicise the archive under the motto 'preserving the memory of the past as an instrument of democracy in the present'. The programme ran for two seasons and entered a third. On 22 February 2020, Ephemera was made an Honorary Member of the Order of Merit. The archive continues to receive estates and contributions, including nationally significant collections such as those of Francisco Sá Carneiro, José Fonseca e Costa, Nuno Rodrigues dos Santos, Vítor Crespo, Carlos da Fonseca, José Carlos Ferreira de Almeida, Rodrigo Sousa e Castro and Francisco Ferreira ('Chico da CUF').
