“…Search engines, web scraping tools, and optical character recognition software have furthermore facilitated the processing of documents much faster than human capacity, while also enabling researchers to recover new perspectives of key historical events (Crossen-White 2015). Yet, in spite of the advantages, it is still important for researchers to remain critical and evaluate whether (and to what extent) the digitization of materials is selective, as is often the case in digitized archives, as well as how digitally accessing materials may affect one's evaluation of them (Voges, Märgner, and Fingscheidt 2009). Many archives have had limited resources to fully digitize their collections, and digitization requests submitted by researchers can (and have) generated a backlog that archives and libraries struggle to process, especially in the wake of pandemic closures (Miller 2013).…”

The COVID-19 pandemic has underscored the unpredictability and instability of fieldwork as a method for data collection. As the pandemic prompted unprecedented political dynamism and social and economic disruptions at both domestic and global levels, in-person fieldwork became challenging, if even possible, in the two years following March 2020. While scholars are again using traditional fieldwork methods, we have seen an increased use of digital tools to conduct research remotely since the pandemic due to international travel bans and social distancing measures. Although not yet widely discussed, these new approaches pose new ethical questions as understandings of both our “fields” and “homes” evolve. In this paper, we stress the need for scholars to reconsider how we conceive of our ethical obligations in situations wherein we have conducted research without ever physically accessing our field sites or interacting in person with our participants. We particularly urge researchers to re-evaluate their ethical responsibilities around transparency and replicability in the dissemination and publication of findings when engaging in fieldwork “from home.” These considerations were necessary prior to 2020 but are especially relevant within the context of the pandemic as scholars enter new field sites remotely or return to those previously visited in person. As a result, this paper starts a critical conversation about ethical practices in remote and digital fieldwork, which will continue to prove significant as digital and remote methods are used for data collection in a post-pandemic world.

“…Due to the limited shelf life of the carrier media and constant rapid technological advancements, data can become unreadable or has to be migrated every few years with high costs and potential data loss. [ 1 ] The current dependence on digital objects, especially with regard to rapidly changing technologies and the regular need to migrate data, as well as the vulnerability of digital storage media to failure or attacks that lead to data loss or manipulation, is not sustainable in the long term. There is a high risk that digital recordings will only be partially readable in the future and will at best provide an incomplete, if not distorted, picture of the data.…”

“…[ 5 ] These archival films have a life expectancy (LE) of several hundreds of years, given appropriate temperature and humidity; [ 6 ] they support the storage of both analog and digital data and are absolutely forgery‐proof. [ 1 ] However, if storage conditions are not ideal, they can potentially still be damaged by mechanical, microbiological and biochemical impacts. Thus, the materials the films consist of have to meet very high standards regarding their durability and resistance to environmental influences in order to achieve a maximum service life.…”

The aim of this study was to investigate the suitability of selected essential oils as more environmentally friendly, sustainable antimicrobial agents in photographic films for long‐term data storage. For this purpose, essential oils of oregano, thyme, and lemongrass were added in concentrations ranging from 0.4% to 4% to the gelatin comprising a protective layer for photographic microfilms. The emulsions were analyzed via UV‐Vis for their optical transparency, then tested for their antimicrobial efficacy against Bacillus subtilis, Staphylococcus hominis and Staphylococcus epidermidis. Thin coatings generated by spreading and drying the emulsions onto photographic film substrates were then characterized morphologically via SEM before and after standardized artificial aging procedures. It was found that oregano oil at a concentration of 0.4% maintained the optical and physical properties of the emulsion and proved highly effective against all tested bacteria. Thyme and lemongrass oil also exhibited some antimicrobial activity, however, were not able to inhibit the bacterial growth completely. At higher concentrations of the oils, the gelatin coatings cracked after artificial aging, which makes them unsuitable for the application. To conclude, selected essential oils like oregano oil can be used as an effective antimicrobial agent without compromising the quality of the photographic films.Practical applications: The results of our research can be applied directly to the manufacturing of photographic films, specifically ones intended for long‐term data storage. Furthermore, many applications of gelatin or related materials which require antimicrobial activity, such as food packaging, could be enhanced by the addition of essential oils.
