Doing away with the "judgmental function" of his personal appraisal of the first edition, the author valued the "informative function" and expanded the corpus of his work considerably, namely through the inclusion of periodicals and serial publications.
An interesting and important work was published in 1949 by António Horta e Costa. With a considerable volume of information (122 pages), Subsídios para a História do Cinema Português [Subsidies for the History of Portuguese Cinema] (Empresa Literária Universal [Publishing House], 1949) is an excellent chronological list of films and written production on cinema in Portugal relating to the preceding 50 years (1896-1949). Similarly, a few years later, a pivotal work dedicated exclusively to the film press emerged, namely the Breve História da Imprensa Cinematográfica Portuguesa [A Brief History of the Portuguese Film Press] (Clube Português de Cinematografia [Portuguese Cinema Club], 1954), by Henrique Alves Costa. Less significant, but equally valuable, was the contribution of journalist Chitónio Montalverde, with Nomes e Números do Cinema Português [Names and Figures in Portuguese Cinema] (Author’s Edition, 1969) and Os Primórdios do Cinema Português [The Beginnings of Portuguese Cinema] (Author’s Edition, undated), where the author added new data to under explored biographies and filmographies.
The field of film criticism also offered important contributions geared towards a critical history of Portuguese cinema. Among the more enlightened critics, Manuel de Azevedo contributed most to enriching the debate around the cinematographic phenomenon in Portugal. The approach of this author to Portuguese cinema began through his collaboration in several periodicals, in a journalistic, critical and reflexive style that generally sought an initial contact with aspects of the cinematographic phenomenon. The first contribution was published in a separate volume entitled Ambições e Limites do Cinema Português [Ambitions and Limits of Portuguese Cinema] (Seara Nova [Journal], 1945), bringing together a collection of articles previously published in the Seara Nova journal.
