Here is a technique I have used a few times. It relies on the record being flat (not warped) otherwise it makes things very difficult.
I place all the pieces on a hard flat surface (kitchen counter for example) and bring the pieces together tightly and by hand. I use something heavy (a few large unopened tin cans for example) to hold things together. I have a hand held microscope to check that the first outer groove is aligned correctly. The adjustment part is what takes time. Once everything is in place, I use a needle dipped in cyanoacrylate (crazy glue) so that it forms a small drop on the end. By applying the needle to the outer end (on the edge of the record) of the crack(s) the glue is sucked into the crack by capilarity. It may not reach throughout but it is usually sufficient to hold things together well enough for one more play.

I just had a telephone call from someone who wants to edge-glue a broken 78 back together. It is broken in 4 pieces, but the breaks miss the label.
The record is for exhibit, it will never be played. It was described as a 'master'. They have another copy of the record that can be played. The important thing about the broken record is a 'signature' on the record. I am guessing it is a famous signature? The caller says the breaks are 'clean' so there is no grove missing. It is a clean break (not a laminated Columbia).
They are looking for someone who knows how to put the record back together so it looks good. This probably means edge gluing, perhaps with 99 percent ethanol or some other solvent or super glue. They will pay a professional for this service.
