I'm wondering, as this is just for display, why use glue at all? Why not cut a tight matte out of non-acid board stock, then put that and the record under glass in a frame? The glass and the matte will hold the disc together for display purposes.

It used to set when it was starved of oxygen, but in later years it sets when subjected to humidity. Pre-moisturing the broken parts is no good, because then it sets before the capillary action has completed. The good thing was that the old type had a very low viscosity and would really penetrate a narrow interstice, where it would set because the oxygen was not available to the surface. Possibly you may still get professional types that work according to this principle, but some of them are dependent on certain metals being present instead. Obviously the gel types are no good! However, the question was not concerned with replay but with display, and here a warning is in place: the fumes from the liquid cyanoacrylate will attack the surface of the shellac compound of the record and a repair will be very visible. For display purposes it would conceivably be possible to support most of the edge all the way round, and a polyvinylacetate cement (possibly diluted somewhat with distilled water) could perform the slight attachment needed between pieces. However, cracks would still be evident. So, cheating could be resorted to: make a first-class colour print of the original label and stick that on a similar whole record. I stress similar: it must have run-in and run-out grooves that look more or less than the original, or someone will pick up the strange appearance. Kindest regards, George
