In this very extensive online library, we present a selection of reference articles from our Newsletter, and a number of additional articles specifically produced for this website. We hope this information will provide both enjoyable reading and will help you better understand your tortoise or turtle's needs. Feel free to link to these pages from your own site. New articles are added regularly, so check back from time to time for updates. These articles are grouped together by subject to make browsing easier. Do not forget to check our CARESHEET section as well, which now includes printable versions of basic information on many species, and a variety of posters, notices and other resources in downloadable PDF format. Please note that where veterinary treatmens and/or drug dosages are discussed these are for general educational purposes only. If you have a sick tortoise, consult a qualified veterinarian. We make this information available because in our opinion, the better informed keepers are, the better they are able to recognise serious illnesses and the better able they are to evaluate veterinary treatments which may be suggested.
