Logos Bible Software uses the Libronix Digital Library System. Most of Network Fellowship's teaching materials are also available in this format to allow for easier cross referencing and notes with Bibles, commentaries and other material. If you are interested in trying out the software a free download along with a number of books is available via Nelson Ministry Services (click here) . Once you have the software installed all you need is the books and the most cost effective means to make your initial investment in books is by purchasing one of their library products. The list of available resources include multiple versions of the Bible, a range of commentaries, Bible dictionaries and other study helps, books to help with discipleship and Christian living, apologetics, theology and much more. Click here for a list of what books you get for each level.
