After the initial flurry of interest, government reports rarely receive the attention they deserve. Often based on detailed research, the information they contain is largely inaccessible, even when published in digital form, due to the lack of indexes. After briefly examining the extent to which such reports are indexed (and why they are usually not indexed), the background to and publication of the much-anticipated Mueller report on Russian interference in the US 2016 election is outlined. The inadequacies of several independently published editions are considered and the case is made for indexing the report, despite not having been commissioned to undertake this task. The indexing process is outlined, especially dealing with the metatopic, Donald Trump, and the redacted sections, and possible future developments are suggested. The online index is available at https://www.muellerreportindex.net.
