You are essentially building a panoramic - or stitching photos together. You can take a look at:
http://www.linuxjournal.com/article.php?sid=7295

It shouldn't be too hard to do what you want manually as well. 1. Open A.jpg
2. Image->Canvas Size (increase canvas size in whatever dimension needed) 3. Layer->Layer to Image Size (your A.jpg layer is now the same size as the canvas)
3B - or create a new layer after increasing canvas size, then paste into the new layer (in step 5).
4. Open B.jpg, Select All (Ctrl-A), Edit->Copy (Ctrl-C) 5. Move to A.jpg image, paste (Ctrl-V). 6. Move B.jpg layer around (name it so it remains a separate layer rather than merging down when you anchor it). You might want to decrease opacity to 50% so you can line up with A.jpg.

You are right.
It is very simple, although may nto be intuitive at first - just because the other programs don't get it.

I have four seperate images of a map which has been scanned in four sections. I now want to join the four images together in digital form to reproduce the original map in its entirity.

I am getting very lost in layers and not getting far. I have used one image as the base layer and tried to expand the layer boundaries to allow for the other 3 images, but somehow I just don;t seem to be able to work out how I can paste the other 3 images into the resized boundary.

Ok, make sure you resize the "canvas size" not the base layer (image->Resize Canvas) , not layer boundaries.

Them, focus on the other image, pick the thumbnail of the desired layer on the "layers" dockable dialog, and drag this thumbnail to the image were you will merge everything. There you are ---the dragged layer is instantly pasted in the image.

For extra ease of use, try using the key to teporarily switch to the move tool while doing something with the other tools.

I am using Gimp version 2.0.1.

I am new to Gimp and I am getting very confused trying to do something I am sure is very simple.

I have four seperate images of a map which has been scanned in four sections. I now want to join the four images together in digital form to reproduce the original map in its entirity.

I am getting very lost in layers and not getting far. I have used one image as the base layer and tried to expand the layer boundaries to allow for the other 3 images, but somehow I just don;t seem to be able to work out how I can paste the other 3 images into the resized boundary.

If you are going to be doing this more than once you should probably try this tool for creating Panoramic images in the Gimp: http://www.shallowsky.com/software/pandora/

This section of Grokking the Gimp might help too (but I should warn you I have not read it myself yet though)
