According to the analytics, a lot of users come to my site looking for the Searching for Sherlock concordance. It looks like that site is down for good, but there are freely available alternatives, like AntConc and Voyant Tools. For those with some programming experience (Python, Bash), I also recommend the Natural Language Toolkit (NLTK).
Before getting started, please download the canon and lemmatization and stop-word lists from this Google Drive directory (there is also a useful guide to AntConc). Then extract the files from the “holmes” ZIP, but keep the texts together in a “holmes” folder.
After opening AntConc, you’ll probably want to add the lemmatization and stop word lists under Settings > Tool Preferences:
Select Open Directory and choose the “holmes” folder to load the stories and novels:
Finally, select Word List and Start to create a word list or click concordance to start searching.
You can also upload that directory (folder) to Voyant Tools for further analysis and visualization.
