Introduction: Finding suitable research data repositories that best match the technical or legal requirements of your research data is not always an easy task. This paper, authored by Stephan Buddenbohm, Maaikew de Jong, Jean-Luc Minel and Yoann Moranville showcase the demonstrator instance of the Data Deposit Recommendation Service (DDRS), an application built on top of the re3data database specifically for scholars working in the Humanities domain.

Introduction: The indispensable Programming Historian comes with an introduction to Term Frequency – Inverse Document Frequency (tf-idf) provided by Matthew J. Lavin. The procedure, concerned with specificity of terms in a document, has its origins in information retrieval, but can be applied as an exploratory tool, finding textual similarity, or as a pre-processing tool for machine learning. It is therefore not only useful for textual scholars, but also for historians working with large collections of text.
