The old mycetophild handbook published by the RES in 1980 included various subfamilies (most of which have now been elevated to family rank). It did not cover the Mycetophilinae (which have recently been covered by Peter Chandler's new 2022 Handbook). Nor did it include the Sciaridae, which were the subject of Freeman's Handbook, published in 1983. There has been talk about a new sciarid handbook, but as far as I know, this is not yet anywhere near completion. Peter may be able to tell you more.
