The nine main corpora have exactly the same architecture and interface, which allows users to carry out the following types of searches. One of the important advantages of our corpus architecture is that with one simply query and one click, users can analyze variation by comparing different sections of a corpus; e.g. genres in COCA or BYU-BNC, dialects in GloWbE (or between corpora from different countries), or across time periods (COHA, TIME, recent changes in COCA, and Google Books (Advanced)).

Visualization. You can see (examples with end up V-ing): Limiting and comparing sections
1) a chart with the overall frequency of all matching strings
2) the individual strings (overall - all sections)
3) individual strings (in each section of the corpus: genre, dialect, or time period)
1. You can also limit the search to just particular sections of the corpus (e.g. hard [nn*] in Fiction)
2. More importantly, you can compare between two sections of the corpus (e.g. hard [nn*] in FIC vs ACAD) -- either by genre, dialect, or time period.
