A data storage and retrieval system such as a robotic library has a large plurality of removable storage media, such as tape cartridges, for purposes of I/O. To enhance performance and reliability of the library, a thermodynamic model of the library is constructed and stored in the library, and environmental conditions such as the temperature, humidity, and flow rate of cooling air coming into, flowing through, and leaving the library are monitored. The thermodynamic model of the library includes an acceptable operating range for the library in a psychrometric chart; and the product of the effective thermodynamic mass and specific heat of the library.

The lumber handling apparatus of claim 10 wherein, wherein the bridging member is located in a position such that, upon descending, the lumber support mechanically displaces the bridging member into a position wherein the bridging member projects downwardly past the lower end of the upstream bin wall. 12. The lumber handling apparatus of claim 9 wherein the bridging member is movably attached to the upstream bin wall. 13. The lumber handling apparatus of claim 9 wherein the bridging member is movably attached to the second gate. 14. The lumber handling apparatus of claim 1 wherein the conveyor comprises a plurality of longitudinally extending, transversely spaced apart conveyor elements and the first gate comprises a plurality of transversely spaced apart, parallel, bin arms separated by the conveyor elements. 15. The lumber handling apparatus of claim 14 wherein the plurality of bin arms are connected by a transversely extending torque member. 16. A method for operating a lumber handling apparatus comprising a bin comprising upstream and downstream bin walls, the method comprising: placing a quantity of lumber on a downwardly movable lumber support surface in the bin between the bin walls; moving a gate to an upright position wherein the gate substantially blocks a gap between a conveyor and a lower edge of the downstream bin wall; lowering the lumber support to a discharge position; moving the gate downwardly to a lowered position below a level of the conveyor; and, carrying the lumber on the conveyor downstream from the lumber support and over the gate.
