O'Reilly Media Inc.
O'Reilly was the first publisher to sponsor NVMUG with review books.
NVMUG members receive a 40% discount of print and 50% off ebooks when we order from O'Reilly.com and enter the discount code DSUG.
Free shipping on orders greater than $29.95.
O'Reilly's book review guidelines tell you how to get started.
O'Reilly is also a leader in setting up conferences and otherwise promoting improvements in development of computer programming and communications systems. Much of this work is in more advanced areas that I do not understand.
