Anderson and Greenwood Pressure Relief Technical Manual- This 68 page manual from Anderson and Greenwood and Tyco is fantastic.
Crosby Pressure Relief Valve Engineering Handbook - A 93 page publication-includes fundamentals of relief valve design, terminology, valve sizing and selection - a very handy publication from Crosby and Tyco
Valve Sizing & Selection - This link provides valve sizing and selection software programs for Anderson and Greenwood, Crosby, Yarway and Varec- From Tyco Flow Control North America
Safety Selector Valve - Dual Pressure Relief Device Systems - Anderson Greenwood developed the patented, Safety Selector Valve in response to the growing demand for cost-effective, dual pressure relief valve and/or rupture disc installations in today’s process industries. The Safety Selector Valve is designed specifically to function as an effective ‘switchover’ device that permits routine or emergency servicing of redundant pressure relief devices with no process interruption, thus providing continuous system overpressure protection.

Selection
and Sizing of Pressure relief Valves - Randall W.
Whitesides - This is an excellent document - The function of a pressure relief
valve is to protect pressure vessels, piping systems, and other equipment from
pressures exceeding their design pressure by more that a fixed predetermined
amount. The permissible amount of overpressure is covered by various codes and
is a function of the type of equipment and the conditions causing the
overpressure. It is not the purpose of a pressure relief valve to control or
regulate the pressure in the vessel or system that the valve protects, and it
does not take the place of a control or regulating valve. Proper sizing,
selection, manufacture, assembly, test, installation, and maintenance of a
pressure relief valve are critical to obtaining maximum protection.
