Presented below is a collection of TOS episode screenshots that provide some good views of Mr. Spock's workstation on the U.S.S. Enterprise NCC-1701 Bridge; from which access to the starships Library Computer system could be gained and the Ship's Sensors and Scanners could be controlled. As Mr. Spock served as First Officer and Science Officer of the Enterprise, this workstation also featured a Science and Technology Functions Patch-In Panel (the large curved panel on the far right in the photo immediately below.) Some button layouts and panel designs were modified over the course of the series, on occasion to accomodate the storyline of a unique episode; and a couple of these design variations are illustrated and noted below. But first, the Science Station from several different perspective views ...

"Fascinating!"
The original design of the Library Computer Control Panel incorporated a series of 6 triangular buttons, as seen in the early first season episode "Balance Of Terror" ...
The more familiar design, as seen in the third season "Day of the Dove" ...
For most of the TOS episodes, the Library Computer Audio Output device, (sometimes called a Speaker :-) had its normal cloth backing ...
In the episode "Let That Be Your Last Battlefield", the speaker grille was replaced with the Starship's Self-Destruct Panel (a previously undescribed command feature of the Science Station) ...
In the episode "This Side of Paradise" a closeup camera pan across the deserted Science Station's control surfaces is provided. Below are a series of 5 screenshots taken of this scene ...
