This theme issue has two primary goals: to illuminate the underdeveloped or faltering areas of the discipline as they relate to archaeological collections and to offer tangible paths forward to address the systemic problems identified as they impact the future of archaeology. Present-day archaeology is complicated due to its many sectors of practice: academia/faculty; cultural resource management; federal, state, and local government; tribal governments and communities; descendant communities; students; the general public; and different types of archaeological repositories. Given this complexity, it can be difficult to identify the expectations (and realities) of each sector, which, if better understood, would help illuminate the nuances of preservation, accountability, discoverability, and use of archaeological collections across the discipline. Without a solid understanding of these nuances, efforts to advance the discipline are undermined. This introduction provides an overview of the articles that address emerging and urgent issues and offer viable steps forward. These challenges include the interrelationships between ethics, collaboration, and training; the preservation and management of digital records and data; collections discovery and reuse; collections-based research; training in material culture; making collections knowable to constituencies outside archaeology; preparing for repatriation from a management perspective; and the intricacies of the archaeological digital data system.

The articles compiled here offer examples of how the impacts of anthropogenic climate change in coastal settings are monitored and measured, how the broader public can be involved in these efforts, and how planning for mitigation can come about. The case studies are drawn from the southeastern United States and the British Isles, and they indicate the great potential that cooperating communities of practice can offer for addressing climate-change impacts on cultural heritage.

There is a current and projected dearth of individuals with the required skills and education to become professional archaeologists. Because of this, the discipline should consider underlying causes leading students to have a lack of interest in pursuing archaeological careers. Social cognitive career theory posits that self-efficacy, expected outcomes, and goal mechanisms mediate a student's career-relevant interest and aspirations. To understand undergraduate students’ perceptions of archaeological careers, we surveyed and interviewed students enrolled in an introductory course in biological anthropology and archaeology at a regional comprehensive university in the United States. Students completed surveys at the beginning and end of the course, and some students volunteered for an interview. Survey results revealed no significant changes in career interest from the beginning to the end of the course. Interview data indicated that taking the course gave students a better appreciation for archaeology, and none interviewed felt less likely to pursue a career in the discipline. We identify persistent perceptions that students held about the discipline that may dissuade them from considering archaeology as a viable career option, and we provide recommendations that may help attract more students to careers in archaeology.

Archaeologists frequently use written guidelines such as site manuals, recording forms, and digital prompts during excavations to create usable data within and across projects. Most written guidelines emphasize creating either standardized datasets or narrative summaries; however, previous research has demonstrated that the resulting datasets are often difficult to (re)use. Our study analyzed observations and interviews conducted with four archaeological excavation teams, as well as interviews with archaeological data reusers, to evaluate how archaeologists use and implement written guidelines. These excavation team and reuser experiences suggest that archaeologists need more specific best practices to create and implement written guidelines that improve the quality and usability of archaeological data. We present recommendations to improve written guidelines that focus on a project's methods, end-of-season documentation, and naming practices. We also present a Written Guidelines Checklist to help project directors improve their written guidelines before, during, and after fieldwork as part of a collaborative process. Ideally, these best practices for written guidelines will make it easier for team members and future reusers to incorporate their own and others’ archaeological data into their research.

A major problem in collections management is the lack of training about collections in all facets of archaeology. Ignorance about both ethical obligations and practical steps associated with collections is arguably the leading contributor to the ongoing curation crisis. This work summarizes shortcomings in collections training in academia and in cultural resource management, and it proceeds to identify some steps that can be taken to provide training for students and professional archaeologists. The overriding argument is that more training in all aspects of collections is absolutely essential to addressing and beginning to mitigate the overwhelming problems the discipline faces in caring for archaeological collections.

The impact of microbiologically influenced corrosion on underwater archaeological sites has spurred recent advancements in research examining the link between microorganisms and historic preservation. Although the microbiomes of steel shipwreck sites have been the subject of DNA sequencing studies and other interdisciplinary investigations, aluminum submerged aircraft wrecks, a prominent symbol of World War II, have yet to be the focus of similar research. This article represents the initial attempt to fill this void by describing a biofilm collection method used to obtain samples for DNA sequencing from World War II aircraft sites off Hawaii. Rather than relying on proxies for microbial growth on wrecks or on destructive sampling, the focus is on a methodology that is productive but minimally intrusive. The protocols resulted in the successful collection of in situ biofilm samples from four submerged aircraft wrecks. The methodology was found to be affordable, time efficient, and reproducible, thus feasible for archaeological site management. The development of viable in situ collection methods for biofilm should aid efforts to empirically assess the relevancy of microbiologically influenced corrosion to submerged aircraft while enabling longitudinal studies of microorganisms that potentially affect site preservation.

Field schools are foundational training for archaeologists and the corresponding methods for instruction are largely consistent within the discipline. The expectation is that at some point early in their careers students will enroll in a field school. To participate, students must pay summer tuition, dedicate a minimum of four weeks (usually longer) to full-time fieldwork, and in many cases travel to remote locations. The reality is that for many students such expectations make field school participation an impossibility—and ultimately make archaeology a nonviable career option for students from historically underrepresented backgrounds. Offering local field opportunities within the context of a regular school year alleviates those problems. A recent field school in north Idaho demonstrated how traditional field school structure excludes many students and how archaeologists can adjust instruction to make field training more accessible to students.

Over the last decades, archaeology has experienced a transformative revolution in the wake of the digital that has shaped the ways in which it is researched and published. A key concept, openness, has emerged from this shift. This article explores digital approaches to data management conducted within the framework of the PERAIA project, which provides a comprehensive open database and a web application that integrate data on archaeological heritage spanning from late prehistory to antiquity, covering the Aegean area (Crete) and northeastern Libya / northwestern Egypt (Marmarica). We used a methodology that integrates legacy data with historical aerial and satellite imagery to identify archaeological features in the landscape, thereby enriching them with associated environmental and historical (meta)data. Our open data practices reflect a commitment to open science, in which digital technology and the LOUD+FAIR principles have been at the core of the project to achieve data openness, fair access to information, and enhanced data reusability potential.

For nearly a decade, there has been recognition of the need for an African American Graves Protection and Repatriation Act (AAGPRA) or similar legislation. Experiences from implementing the Native American Graves Protection and Repatriation Act (NAGPRA) have shed light on challenges that prevent practitioners from achieving the informed, respectful, and expeditious return of remains. Given the likelihood of federal legislation addressing the repatriation of persons of African descent and acknowledging the hurdles that practitioners may face if and when it is passed, we offer a practical model, START, to reorient our understanding of success to recognizing that incremental progress is still forward movement. The model is organized into five stages and is presented with context from NAGPRA, along with suggested steps that practitioners can take at each stage to help build on their success. The START model is a straightforward and practical checklist approach that helps practitioners recognize the victories achieved in small steps that could be hidden or prevented by misguided but well-intentioned attempts at perfection. It is directly applicable to preparation for repatriation but has utility for any curation or collections management context.

Archaeogaming is an area of increasing interest within archaeology. As archaeogaming's theory and practice are being fleshed out, it is worth considering if there are parallels to traditional archaeological methods within the study of video games. Here, we examine one such possibility: is there an archaeogaming equivalent to experimental archaeology? As a case study, we explore the system used for the mid-1980s development of an unreleased video game prototype for the game company Activision. Through examining this development system, whose use would be otherwise invisible in the finished software artifact, we demonstrate how we have both reconstructed a seemingly lost piece of the system virtually and used this reconstruction for experiments. The methodology we describe can be applied to digital artifacts within contemporary archaeology beyond the scope of video games, and it illustrates some key differences between studying physical and digital artifacts.

The North American Heritage at Risk (NAHAR) collaborative, which formed during the COVID-19 pandemic, allowed for heritage-at-risk partners to shift from reactive to proactive strategies. The result was the creation of the NAHAR research pipeline to respond to landscapes at risk. The pipeline includes modeling of environmental changes to the landscape; monitoring sites to verify location and assess condition; meeting with the public, descendant community, land managers, and transdisciplinary experts in their field to discuss climate change impacts to their heritage in the next 10 years; methodizing by means of a workflow organizer using data from the modeling, monitoring, and meeting; and when appropriate, mitigating areas identified during the methodizing process. In 2020, the Florida Public Archaeology Network—along with partners in Georgia, South Carolina, Washington, Texas, and Louisiana—began the Science Collaborative People of Guana project at the Guana Tolomato Matanzas Estuarine Research Reserve (GTM NERR) north of St. Augustine, Florida. Using a collaborative science mindset, the project team applied the NAHAR pipeline to gain a better sense of how resources were used in the past and how they currently are being used by communities to ensure responsive resource management and relationship building with visitors, descendants, and other community stakeholders, such as the Gullah/Geechee Nation. This article will provide the building blocks for other collaborative teams to follow the NAHAR pipeline and share lessons learned from the two-year project.

This article discusses ethical frameworks for planning and implementing composite research in the United States. Composites, defined here as archaeological materials with multiple genetic sources, include materials such as sediment, coprolites, birch pitch, and dental calculus. Although composites are increasingly used in genetic research, the ethical considerations of their use in ancient DNA studies have not been widely discussed. Here, we consider how composites’ compositions, contexts, and potential to act as proxies can affect research plans and offer an overview of the primary ethical concerns of ancient DNA research. It is our view that ethical principles established for analyses of Ancestral remains and related materials can be used to inform research plans when working with composite evidence. This work also provides a guide to archaeologists unfamiliar with genetics analyses in planning research when using composite evidence from the United States with a focus on collaboration, having a clear research plan, and using lab methods that provide the desired data with minimal destruction. Following the principles discussed in this article and others allows for engaging in composite research while creating and maintaining positive relationships with stakeholders.

Archaeologists are taught about the importance of professional recordation and our ethical obligations to those associated records and data. These teachings imply that practitioners are meeting a professional standard of recordation that will stand the test of time, but the ongoing digital revolution is changing the way records and data are created and preserved. Best practices for the management and use of digital archaeological records have been published, and devoted digital archives offer these services. However, the ability of traditional archaeological repositories to adopt best practices or pay for digital curation is poorly understood. This article presents the results of a survey asking how the flood of digital records and data has impacted the ability of archaeological repositories to collect, manage, preserve, use, and make accessible digital archaeological records and data. Are repositories adopting the best practices that have been outlined? What kinds of challenges do repositories face regarding digital records and data? Are they being overcome successfully? The survey results offer a snapshot of current practice and point to future directions that should be pursued to ensure that the discipline is meeting its professional obligations.

This article aims to expand the scope of experimental archaeology to emphasize multilevel variation and interactions across the levels of perception, actions, and outcomes. Such an approach, loosely formulated as the Perception-Process-Product (“Triple P”) framework, offers a more grounded and richer explanation of the past archaeological record. It consists of three principles: (1) acknowledging the inherent trade-off between control and generalizability in the experimental research design; (2) encouraging collaborative projects that involve geographically diverse and nontraditional research participants, such as hobbyists and novices; and (3) adopting a workflow that normalizes the collection and curation of ethological and ethnographic data in experimental projects. Serving as a heuristic device, this alternative mode of knowledge production is highly flexible in nature, where each single component is detachable as dictated by individual research questions.

In March 2023 the EU-funded CHERISH project published its free user-guide and methodology for investigating heritage and climate change in the coastal and maritime environment (Barker and Corns 2023). This paper provides an overview of the publication, specifically the CHERISH toolkit – the 15 approaches employed by the multi-disciplinary project to investigate at-risk heritage sites in Wales and Ireland. Using the eroding coastal hillfort of Dinas Dinlle in Wales as a case study, the toolkit which combines air, land and sea-based investigation techniques is highlighted. This article will assist users going forward in identifying relevant approaches to the study of their own at-risk sites. It is relevant to a wide-ranging audience anywhere in the world, taking into consideration a variety of requirements such as the environment, budget, and outputs.

Experimental stone tool replication is an important method for understanding the context and production of prehistoric technologies. Experimental control is valuable for restricting the influence of confounding variables. Researchers can exert control in studies related to cognition and behavior by standardizing the type, form, and size of raw materials. Although standardization measures are already part of archaeological practice, specific protocols—let alone comparisons between standardization techniques—are rarely openly reported. Consequently, independent laboratories often repeat the costly trial-and-error process for selecting usable raw material types or forms. Here, we investigated various techniques and raw materials (such as hand-knapped flint, machine-cut basalt, manufactured glass, and porcelain) and evaluated them for validity, reliability, and standardizability. We describe the tests we performed, providing information on the individual approaches, as well as comparisons between the techniques and materials according to validity and reliability, along with relative costs. We end by providing recommendations. This is intended as a serviceable guide on raw material standardization for knapping experiments, including existing strategies and ones so far undescribed in the experimental archaeology literature. The future of this field would benefit from developments in the relevant technologies and methodologies, especially for those that are not yet widely available or affordable.

Web scraping, the practice of automating the collection of data from websites, is a key part of how the internet functions, and it is an increasingly important part of the research tool kit for scientists, cultural resources professionals, and journalists. There are few resources intended to train archaeologists in how to develop web scrapers. Perhaps more importantly, there are also few resources that outline the normative, ethical, and legal frameworks within which scraping of archaeological data is situated. This article is intended to introduce archaeologists to web scraping as a research method, as well as to outline the norms concerning scraping that have evolved since the 1990s, and the current state of US legal frameworks that touch on the practice. These norms and legal frameworks continue to evolve, representing an opportunity for archaeologists to become more involved in how scraping is practiced and how it should be regulated in the future.

Community Coastal Zone Assessment Surveys (CCZASs) conducted on the Scottish coast aim to characterize and assess the significance, condition, and vulnerability of coastal archaeology and to prioritize assets most at risk. Two key differences from earlier coastal zone assessment survey methods are the use of coastline vulnerability models to target fieldwork and the involvement of the public in the surveys. This article details the methodology used to plan for, carry out, and disseminate results of the surveys, including the following: evaluating and targeting coastlines in a GIS framework to focus new coastal surveys in areas most susceptible to erosion, using SCAPE's coastal archaeology recording mobile application as our survey tool, managing data through SCAPE's Sites at Risk portal, involving local volunteers, and disseminating findings and data flow into regional and national historic environment databases. We discuss results and reflections from surveys of the Highland, Moray, and Aberdeenshire coastlines conducted in 2022 and conclude with general principles applicable beyond Scotland.

Archaeologists seek to improve our understanding of the past by studying, preserving, protecting, and sharing nonreplaceable archaeological resources. Archaeological collections hold information that can assist these aims as long as they are properly cared for, identified, and accessible. One of the most serious barriers is the lack of large-scale coordinated efforts to make archaeological collections findable and accessible. This article suggests that developing and implementing the use of a standardized set of attributes regarding collections provides solutions and strategies to find collections. These attributes can connect and standardize existing archaeological collections from a variety of sources (federal and state agencies, CRM firms, Indigenous and descendant communities, and academic departments), serving the profession in multiple ways. Most critically, the baseline data can be synthesized to inform and direct priorities for future fieldwork, thereby decreasing redundancy in archaeological collections and improving curation efforts nationwide. Such efforts would also provide a resource to students and researchers looking to understand and interpret the past at multiple scales by encouraging more collections-based research and less archaeological site destruction. Access for descendant communities will also be improved with information about their cultural heritage. This, in turn, encourages transparency and collaboration between those communities and archaeologists.
