Much of the information found in the earlier RepRap blogs is still very relevant today and makes for invaluable reading for anyone interested in developing parts and printers or interested in how the project has reached the state it currently is in.
The following books are collections of these posts repackaged into formats suitable for e-book readers and offline browsing.
Please note that the epub versions are zipped up as the wiki seems not to like having .epub files uploaded.
The contents of the books are generated via a script, consequently some formatting errors may have occurred during creation. Minor errors will not be corrected but please report any major problems to email@example.com. The files are also mirrored at my blog: http://garyhodgson.com/reprap/reprap-developer-bookshelf/
