Welcome to our online store. The RFC Sourcebook is an essential reference to the Request for Comments (RFCs) series of standards documents. We developed this product to organize the RFCs and to provide a convenient and comprehensive guide for these documents and the people who have written them. Our goal is to gather the data scattered throughout the documents and provide the relevant information in an easy to use format for professional programmers and engineers. The documents are organized numerically, by topic, by protocol and by author to provide an efficient cross-reference guide. The RFC Sourcebook is available four times per year on CD in Windows HTMLHELP format. This allows us to provide the 160+ megabytes of data and a search engine in a single compressed 60 megabyte file. For systems that cannot use the HTMLHELP file, we have also provided the contents as a ZIP archive. RFC Sourcebook Vol 10 Number 4 on CD $39.95 Yearly subscrption $99.95
