So I keep sharing different circuit documents as I find them, decided to just wrangle all that together.  Going forward I'll drop IC and other component document stuff here.

Tonight's scan is topical to the forum, this is the June, 1972 issue of the Solid State Devices Handling And Selection Guide from Western Electric:

https://archive.org/details/solid-state-devices-handling-and-selection-guide-june-1972

There is an earlier version of this guide available here:

https://www.telephonecollectors.info/index.php/browse/wiring-diagrams/western-electric/component-specifications/9326-weco-solid-state-devices-handling-and-selection-guide-reduced-ocr

Both detail solid state circuitry devices from WECo such as transistors, diodes, and integrated circuits.  In both cases, basic information is provided but this is not a databook.  Enough information is provided to vaguely use the components, although the WECo engineers at the time insisted referring to the official datasheets for all definitive information.

I luckily do have the 1973 Silicon Integrated Circuit issues, and the Linear Families volume for 1976.  I intend to scan those sometime in the next year, those contain full datasheets.

One thing I'm hoping to establish a bit more info on is the process of products moving from Bell Laboratories to Western Electric.  Bell Laboratories component manuals tended to be published in manila report covers, whereas WECo component literature was a tad more elaborate.  This and the earlier guide were comb bound issues with colorful covers.  The databooks are very '70s Bell System, with a basic Western Electric logotype and the blue and ochre stripes.

Anyway, enjoy, this covers among other things 41* series WECo chips, including their linear and digital logic families.
