The editor of the A Sementeira website would like to thank Dr. Rita Almeida de Carvalho and Dr. Madalena Soares Reis for providing documentation from the Pinto Quartim Collection, kept at the Arquivo de História Social of the Instituto de Ciências Sociais of the University of Lisbon; Dr. Luís Sá, of the National Library, for his close and interested collaboration; Dr. António Louçã, Dr. Joana Dias Pereira, Professors João Freire and Paulo Guimarães for graciously consenting to the inclusion in the website of their articles, chapters, and dictionary entries.

Our thanks to Dr. Alexandre Samis, not only for his thoughtful collaboration, which included correspondence testimonials, but also for his knowledgeable introductory text.

The compilation of monographic studies relied on the help of Mário Rui Pinto, whom we thank for his enormous generosity. We are also grateful to Jorge M. Colaço for making his image collection available to us, allowing the selection of graphic elements necessary for this website.

Finally, we give our gratitude to the associates of the Centro de Estudos Libertários for allowing access to their rich bibliographical collection, and for their ever-present interest in completing this publication.
