The following site IVIS (International Veterinary InformationService) was a very useful resource for me when I was teaching Canine Science and Introduction to Veterinary Medical Science. This is an on-line publisher of veterinary books and proceedings having some 1,673 book chapters and articles. Although many of the articles are technical my students would use them as additional reading and for research papers. And the good news is…these are free! To access them you only need to register. After you register you can have them put you on their email list to receive their newsletter. They send this out occasionally which will help keep you informed as to what new books and articles are available. Hope it is useful to you?
