Here we feature books and websites that we have found either useful or simply interesting as regards to the U.K. beetle fauna. Some books cover the wider European fauna but include a worthwhile amount of information on British species while some are more focused on ecology or other aspects of the subject but all will provide information essential, if not to the casual collector, to the more serious or academically-minded coleopterist. In order to make this section manageable we have consigned books and sites that deal with specific families or groups to the relevant family pages but many of the works in this section will also be useful in this context, more especially those dealing with host plants and fungi etc. We make no attempt to review any of the featured works because we only add those we have found to be good and, in any case, lack of a good review might suggest we have reservations or do not approve of a work. Our broad philosophy is that if somebody puts in the hours to write about beetles and to make that information available then who are we to criticize? Access to entomological bookshops online will provide an almost endless list of works that the U.K. coleopterist will find interesting but of only limited usefulness or desirability, especially when considered against the prohibitive cost of building a library, and many of these, especially of the reprinted-scientific-paper variety, will be out of date and interesting only in passing. The pace of research into beetles has increased significantly in recent decades, especially regarding classification, and changes tend to take a long time to filter down to regional workers, and so the keen coleopterist should be constantly researching online to keep up with events. Regarding our U.K. fauna one could hardly do better than to subscribe to The Coleopterist and join a society or two. For the more academically minded the various journals published by the Royal Entomological Society are essential reading.
