OnLineTexts.com online texts are published on our servers under URLs specific to each academic discipline. For example, our economics sites are published at econweb.com, and our computer science sites will be at compscitexts.com.    We obtain an ISBN for each OnLineTexts.com text. This enables campus bookstores to order from us exactly as they do print publishers.    Keeping current is always a challenge for academic course materials, and this is one area where online texts have a huge advantage over printed texts, ebooks, pdf files and, in fact, any other method of print or electronic publication. We make it as easy as possible to update your sites so that current material can appear as you create it.
