Scientific posters are one of the most common forms of scholarly communication and contain early-stage insights with potential to accelerate scientific discovery. We investigated where posters are shared, to what extent their sharing aligns with the FAIR principles, and how commonly they are reused. We identified 86 platforms hosting posters, with many not assigning persistent identifiers. A total of 150k posters are shared as of 2024 on the 43 platforms where we were able to count, which is relatively low. Looking in more detail at posters shared on Zenodo and Figshare, we found that repositories are not always supporting structured metadata critical for poster discovery, like conference information, and that researchers are not providing such metadata even if they are supported. We also observed that while there is some engagement with posters in terms of views and downloads, citing posters is not yet a common practice. Our recommendations are for the scientific community to encourage poster sharing and reuse and establish clear guidelines to make posters FAIR.

翻译：科学海报是最常见的学术交流形式之一，其中包含早期阶段的研究见解，具有加速科学发现的潜力。本研究调查了科学海报的分享平台分布、其分享实践与FAIR原则（可查找、可访问、可互操作、可复用）的一致性程度，以及再利用的普遍性。我们识别出86个托管海报的平台，其中许多平台未分配持久标识符。截至2024年，在能够进行计数的43个平台上，共享的海报总数约为15万份，这一数量相对较低。通过对Zenodo和Figshare上共享的海报进行详细分析，我们发现存储库并不总是支持海报发现所必需的结构化元数据（如会议信息），而即使支持此类元数据，研究人员也常常不进行填写。我们还观察到，尽管海报在浏览量和下载量方面存在一定互动，但引用海报尚未成为普遍实践。我们的建议是：科研界应鼓励海报的分享与再利用，并制定明确的指南，使海报符合FAIR原则。
