Wood is a natural polymeric material that is an important constituent of many heritage collections. Because of its susceptibility to biodegradation, it is often chemically treated with substances that can be harmful to human health. One of the most widely used wood preservatives was pentachlorophenol (PCP), which is still present in museum objects today, although its use has been restricted for about forty years. The development of non-destructive methods for its determination, suitable for the analysis of valuable objects, is therefore of great importance. In this work, two non-destructive solid-phase microextraction (SPME) methods were developed and optimized, using either headspace or contact mode. They were compared with a destructive solvent extraction method and found to be suitable for quantification in the range of 7.5 to 75 mg PCP/kg wood at room temperature. The developed semi-quantitative methods were applied in the wooden furniture depot of National Museum of Slovenia. PCP was detected inside two furniture objects using headspace mode. The pesticide lindane was also detected in one object. The indoor air of the depot with furniture was also sampled with HS SPME, and traces of PCP were found. According to the results, SPME methods are suitable for the detection of PCP residues in museum objects and in the environment.

Purpose To describe how academic libraries can support digital humanities (DH) research by leveraging established library values and strengths to provide support for preservation and access and physical and digital spaces for researchers and communities, specifically focused on cultural heritage collections. Design/methodology/approach The experiences of the authors in collaborating with DH scholars and community organizations is discussed with references to the literature. The paper suggests how research libraries can use existing expertise and infrastructure to support the development of digital cultural heritage collections and DH research. Findings Developing working collaborations with DH researchers and community organizations is a productive way to engage in impactful cultural heritage digital projects. It can aid resource allocation decisions to support active research, strategic goals, community needs and the development and preservation of unique, locally relevant collections. Libraries do not need to radically transform themselves to do this work, they have established strengths that can be effective in meeting the challenges of DH research. Practical implications Academic libraries should strategically direct the work they already excel at to support DH research and work with scholars and communities to build collections and infrastructure to support these initiatives. Originality/value The paper recommends practical approaches, supported by literature and local examples, that could be taken when building DH and community-engaged cultural heritage projects.
