Introduction: In this blog post, James Harry Morris introduces the method of web scraping. Step by step from the installation of the packages, readers are explained how they can extract relevant data from websites using only the Python programming language and convert it into a plain text file.

It is therefore not only useful for textual scholars, but also for historians working with large collections of text.
