Over the past decade, LLILAS Benson has undertaken post-custodial archival projects in collaboration with partners throughout Latin America and beyond. Post-custodial archival practice encompasses a range of theory and methodology, built on the premise that digital technologies make it possible for collecting institutions like LLILAS Benson to provide access to archival collections from Latin America without taking physical custody or removing them from their original contexts of creation and use.

Through these post-custodial projects, LLILAS Benson staff and partner repository staff work together closely to identify collections of interest, select appropriate digitization equipment, and build metadata collection strategies. The materials are then digitized and described on-site in Latin America by partner repository staff. The digitized collections are then transferred to LLILAS Benson, where they are processed, preserved, and in most cases published online. Because the original collections are often vulnerable or sensitive, frequently touching on delicate human rights issues, long-term preservation of their digital copies is especially important to LLILAS Benson staff and partners in Latin America.

In recent years, the LLILAS Benson team has integrated file fixity checks in all post-custodial projects. When launching a project at a partner site, LLILAS Benson staff now teach project team members the basic principles of digital preservation and the importance of fixity checks, which verify that files have not been altered or corrupted over time. The project teams are taught to create and verify checksums prior to transferring a batch of files to LLILAS Benson, using free software available in Spanish or Portuguese.

These checksums now accompany all file deliveries from project sites, and help the LLILAS Benson team identify corrupted or missing files immediately. These checksums speed LLILAS Benson’s processing and preservation work, allowing the files to be published online and preserved long-term more easily. The checksum workflow also encourages each partner to include fixity checks in any future digitization projects they undertake, thus contributing to the partners’ own digital preservation capacity.

Durante la última década, LLILAS Benson ha emprendido proyectos de archivo de tipo poscustodial junto con socios a lo largo de América Latina. La práctica de archivo poscustodial abarca una serie de teorías y metodologías basadas en la premisa de que las tecnologías digitales hacen posible que las instituciones colectoras como LLILAS Benson provean acceso a las colecciones de archivos de Latinoamérica sin su custodia física o su eliminación del contexto original de su creación y uso.

A través de estos proyectos poscustodiales el personal de LLILAS Benson y sus colaboradores trabajan en estrecha colaboración para identificar colecciones de interés, seleccionar el equipo de digitalización adecuado y desarrollar estrategias de curaduría de metadatos. Los materiales son digitalizados y descritos en Latinoamérica por parte del personal de cada archivo para luego ser transferidos al equipo LLILAS Benson, quien procesa, preserva y publica los materiales en la mayoría de los casos. Debido a que las colecciones originales son a menudo vulnerables o con contenido delicado, y frecuentemente tocan temas relacionados con derechos humanos, la preservación a largo plazo de sus copias digitales es especialmente importante para el personal y los socios de LLILAS Benson en América Latina.

En años recientes, LLILAS Benson ha añadido verificaciones de permanencia de archivos en los proyectos poscustodiales en curso. Con el inicio de cada proyecto en el archivo de los colaboradores, el personal de LLILAS Benson enseña a cada equipo los principios básicos de preservación digital y la importancia de añadir verificaciones de permanencia, que verifican que los archivos no han sido alterados o dañados con el tiempo. Los equipos de los proyectos aprenden a crear y verificar sumas de verificación usando programas gratuitos en español o portugués antes de transferir un conjunto de archivos a LLILAS Benson.

Estas sumas de verificación ahora acompañan todas las entregas de archivos desde el lugar de los proyectos de digitalización y ayudan al equipo de LLILAS Benson a identificar archivos dañados o faltantes de inmediato. Esto acelera las tareas locales de procesamiento y preservación en LLILAS Benson y anima a cada colaborador a incluir controles de verificación en cualquier otro proyecto que puedan emprender en el futuro. Esto a su vez contribuye a la capacidad de preservación digital propia de los colaboradores.

Durante a última década, a LLILAS Benson empreendeu alguns projetos arquivísticos pós-custodiais, em colaboração com entidades parceiras espalhadas pela América Latina e outros lugares. A prática arquivística pós-custodial engloba uma gama de teorias e metodologias assentadas na premissa de que as tecnologias digitais possibilitam a instituições recolhedoras de coleções, como a LLILAS Benson, disponibilizar o acesso a coleções arquivísticas latino-americanas sem necessidade de obter custódia física ou a remoção das mesmas de seus contextos originais de criação e de uso.

Por meio desses projetos pós-custodiais, as equipes de profissionais da LLILAS Benson e dos repositórios parceiros trabalham em contato estreito para identificar coleções de interesse, selecionar o equipamento de digitalização adequado e criar estratégias de coleta de metadados. O material é então digitalizado e descrito pela equipe de repositório da entidade parceira em cada local específico da América Latina. Em seguida, as coleções digitalizadas são transferidas para a LLILAS Bensonm onde são processadas, preservadas e, na maioria dos casos, publicadas online. Devido ao fato de muitas coleções originais serem vulneráveis ou sensitivas por causa de referências frequentes a questões delicadas de direitos humanos, a preservação a longo prazo de cópias digitais é especialmente importante para a equipe da LLILAS Benson e entidades parceiras na América Latina.

Em anos recentes, os profissionais da LLILAS Benson vêm integrando verificações de fixidez de arquivos em todos os projetos pós-custodiais. Agora, ao lançar um projeto em local parceiro, a equipe ensina às equipes do projeto os princípios básicos da preservação digital e a importância das verificações de fixidez para constatar se os arquivos não foram alterados ou corrompidos ao longo do tempo. As equipes de projeto aprendem a criar e verificar as checksums (somas de verificação) antes de transferir qualquer lote de arquivos para a LLILAS Benson, usando software gratuito disponível em espanhol e português.

Essas checksums já acompanham todas as entregas de arquivos oriundos de locais de projetos e ajudam a equipe da LLILAS Benson a identificar imediatamente arquivos corrompidos ou faltando. As checksums aceleram o trabalho de processamento e preservação da LLILAS Benson, permitindo publicar os arquivos online e preservá-los a longo prazo com mais facilidade. O fluxograma de checksums também incentiva cada entidade parceira a incluir verificações de fixidez em qualquer projeto de digitalização a ser empreendido no futuro contribuindo, assim, para a própria capacidade de preservação digital de cada entidade.

LLILAS Benson Partnership with Puebla Archive to Yield Rich Results

Four Centuries of Rare Documents Will Be Digitized

August 8, 2018, was an auspicious day for students of Mexican history. An agreement signed between LLILAS Benson and the Tribunal Superior de Justicia del Estado de Puebla marks the official start of a project to digitize a large collection of archival materials from the Fondo Real de Cholula. Funding for the project comes from a Mellon Foundation grant obtained by LLILAS Benson.

The archives in question, which originate in the Mexican town of Cholula, Puebla State, consist of approximately 200 boxes and span some four centuries, from the 1500s to the late nineteenth century. Once digitized, they will be made available to researchers on an open-access platform by the Benson Latin American Collection and the University of Texas Libraries. The materials document, among other things, how Indigenous residents of Cholula navigated colonial judicial structures unique to their special juridical status.

A Rich Trove of Information

The materials will provide a rich trove of information about the colonial period, referred to in Mexico as la época novohispana. Cholula was one of only nine locations to be designated a ciudad de indios (in contrast, there were 21 ciudades de españoles). Ciudades de indios had a different justice system than others. Indigenous people paid their tribute directly to the king instead of to a colonial intermediary; they enjoyed certain privileges, and they maintained a fully functioning Indigenous cabildo, or council, which ruled alongside the Spanish one. “This allowed for a degree of Indigenous autonomy and exercise of special privileges in the new colonial context,” explains Professor Kelly McDonough of the UT Austin Department of Spanish and Portuguese.

LLILAS Benson might never have known about the collection in question had it not been for McDonough, who identified the collection as a good candidate for digitization. She emphasizes that the digitization of ciudad de indios documents has immense historical significance: “It’s the first time we will be able to understand what Indigenous justice meant in place with a very specific juridical designation and relationship with the king of Spain. We believe that the other eight judicial archives from ciudades de indios burned in the Mexican Revolution.”

“The chronological range of the collection will allow scholars to study how Indigenous practices adapted to Spanish rule, how new practices developed over the course of the early-modern period, and how both Indigenous and Spanish practices further adapted to modern political and legal structures in the nineteenth century,” adds LLILAS Benson digital processing archivist David Bliss.

The Digitization Process

A team of three historians from Puebla and Cholula will work in Puebla to digitize the collection, creating two digital copies—one to remain in Puebla and the other to be sent to Austin for preservation and online publication. In addition, all of the digitized materials will be extensively described using a metadata template developed by LLILAS Benson and its Puebla partners. The historians involved in the project are experts in sixteenth-through-nineteenth-century Cholula.

Dra. Lidia Gómez García of Facultad de Filosofía y Letras at Benemérita Universidad Autónoma de Puebla (BUAP) was instrumental in keeping interest in the project going amid inevitable delays. Together, she and McDonough helped choose the personnel to carry out the important work of digitization and creating of metadata for the collection. LLILAS Benson Director Virginia Garrard relates that the team working with the archives in Puebla feels a deep and personal connection with the material; the fact that they are rescuing their own patrimony from decay is immensely meaningful to them.

Last June 2018, Bliss and LLILAS Benson archivist Dylan Joy conducted a training workshop in Puebla for the digitization team. The team will carry out the project using a DSLR camera and two laptops, as well as the digital photography program Adobe Lightroom. The equipment, purchased by LLILAS Benson with Mellon grant funds, will be donated to the Puebla archive at the conclusion of the project, which is set for early May 2019. Bliss estimates that the project will digitize some 45,000 pages of documents.

The final, digitized documents will be ingested into the Latin American Digital Initiatives (LADI) platform, allowing researchers to form connections between the Fondo Real de Cholula documents and other collections on the platform.

A Groundbreaking Collaboration

Director Garrard, herself a historian, hails this project for bringing to light lesser-known historical actors. “This collaboration represents the lives and voices of groups traditionally omitted from the historical record,” she said. “The signing event highlighted the power of close and horizontal relationships between our two institutions, so clearly evident in the presentations of the young Mexican technical specialists and students who described for us their work with the documents, both as material artifacts and as historical sources.”

Quoted in Puebla’s El Popular, Héctor Sánchez Sánchez, presiding magistrate of the Tribunal Superior de Justicia, noted Puebla’s pride in the collaboration: the digitization of Fondo Real de Cholula is the first digitization project at an institution in the Mexican justice system. “Even more so for those of us who are part of this institution,” said Sánchez, “[the rescue of] this archive can achieve a change in the way we understand history.”
