6 Oct 2022 - The MCRA is delighted to announce that the prestigious Tratman Award for 2020 has been awarded to Rob Taviner for volumes 1 and 2 of Somerset Underground. For 2020 the judges were Joe Duxbury, Chris Howes, Alan L. Jeffreys, Martin Mills and Linda Wilson. The following comes from Chris Howes on behalf of the judges:

The Tratman Award is granted annually to the best publication of the year, including books, journals and even individual articles. This report considers those that appeared in print in 2020. The five judges took into account not only the quality of writing, but also the presentation: the binding, paper quality, printing and not least, accessibility and importance of the content. A phenomenal amount of work went into the compilation of these two volumes, producing a clear and visually attractive format using a clean, simple layout. These are, after all, guidebooks intended to be used in the field, and the degree of thought and planning is evident. That extends to personal visits made to each location together with carefully written descriptions, demonstrating the background research that should be undertaken by any good author. Suffice it to say that the content covers everything relevant to the caves and associated sites of the area. These are outstanding works that deserve all the plaudits they have received.

Tav and the MCRA would like to thank everyone involved in the making of these guides, along with the judges and the other nominees, all of whom produced outstanding work.
