With the last published catalogues (Morgan & Good 1992; and Morgan
1994) the sample of known PNe in the LMC has been doubled, allowing a better study
of the population of these objects in the LMC.
We have provided accurate coordinates and finding charts in a homogeneous way
for the whole sample.
From multiple position measurements of objects lying in the overlapping parts
of the Schmidt plates, we derive an accuracy better than 0
5 (with a
few exceptions) and probably better than 0
3 for most of the objects
lying further away from the plate borders.
This is adequate for most of the follow-up work from ground or space.
It should be added that the material available will easily allow a similar,
accurate measurement for any new object which should be discovered later on.
An application to the identification of IRAS sources in the LMC (which have
themselves poor coordinates) leads to 15 identifications with reasonable
confidence, which will be further observed.
