BPBible is a free, open source Bible study package for your computer. It makes it so that you can read the Bible, view commentaries, look at dictionaries, examine Gospel harmonies, search Bibles, and lots more. With BPBible, you can now study religious matter wherever you are, without needing to carry heavy books.
Features
Bible application: BPBible has many of the features you would expect in a Bible application - Bible, Commentary, and Dictionary support, Bible Search, Scripture tooltips, etc.
Cross verse searching: BPBible uses a proximity based search, rather than a verse-based search. This means that a search can cross verse boundaries, giving a more natural search. It also supports regular expressions and phrases.
Flexible layout: BPBible lets you rearrange your layout, and will remember your layout for you.
Good module support: Due to the use of the SWORD libraries, BPBible can read many different Bibles and other books.
User Notes and Topic Management: BPBible supports taking notes on a passage, as well as collecting all the passages related to a topic into a list and then organising and commenting on those passages.
Free: BPBible is licensed under the GPL (version 2) and is absolutely free.
