FreeEbookCentre.Net
The Free Ebook Centre website offers a mismash of content ranging from PDF books to course lectures and in-depth website tutorials. The content is well-organized, with links for common networking domains, but pay attention to the quality and the age of the content. Some material is old enough that it no longer reflects current thinking about network administration and security.
Easy-to-follow side navigation structure.
Includes class notes and lectures.
Content is significantly hit-or-miss, and is rarely actually an ebook.
Some material is very old—too old to be useful for modern audiences.
EBook PDF
The Ebook PDF site offers PDFs of various books, mostly from academic domains on the web. The Computer Networking directory lists dozens of pages of hits, although searching isn’t easy.
Offers obvious date stamps and content snippets.
Clean interface.
Emphasis on PDF files.
Searching is clunky.
Feels like a clearinghouse rather than a curated collection.
Check the contents carefully—some of the stuff that’s presented as a book is merely a PDF of something tangential, like a course syllabus in one instance.
Free Computer Books.com IT Research Library
The material at the IT Resource Library from Free Computer Books, a partnership with Tradepub.com, is modern—but as a repository of content, it’s a bit of a mixed bag. You’ll find cutting-edge white papers mixed with marketing material.
Clean, easy-to-follow structure.
PDF thumbnails help sort content visually.
Requires per-asset registration.
Lots of trade/marketing materials.
For a good, quick overview of modern technologies or niche topics, it’s a good go-to, but you’ll have to register for each item you download, because your data goes to the original source of the material.
