I have been using LR Classic since version 1, but have not studied the nature of LR catalogues until now.
As new versions of LR Classic appeared, new catalogues have been created automatically, and, sadly, I have been ignorant of this. I now want to merge them all into one catalogue, as per the recommendation in your help text.
Presently, LR Classic catalogues and data files are located as seen in the attached document "LR-Classic_Catalogues and Data Locations.pdf".
I will prefer to have the resulting single catalogue and related data located on the external harddisk, with the original picture files. This is to save space on my laptop's harddisk.
I will be very happy to receive advice on how to go about this in a safe way.

All you have to do is open one catalog, then File->Import From Another Catalog, and select the second catalog. Repeat until all catalogs have been imported into one.
There are some options when you do this, you can read about them here (scroll down to "Import photos from a different Lightroom Classic catalog")
Best to save space is to Import your Photos to the external HD straight out of the camera — don't put photos on the internal disk. You might also want to move the photos to the external drive (instructions)

There is nothing to merge. These 'automatically appearing' catalogs are not really new (different) catalogs, they are upgraded catalogs. That means they are newer versions of the same catalog. Obviously the older versions won't contain your latest images or latest edits, but your current catalog will contain everything.

Thank you for the reply. I am, however confused by the fact that, looking at the file sizes of the catalogues, the latest, current catalogue (Lightroom Catalog-v13-3-2.lrcat) does not seem to contain all the older ones - ref. the attachment to my original post. I am nervous that I may have muddled up something in some of my earlier "manoeuvers". Or, is this not a case of simple arithmetic?

If somehow muddling up something in LrC is a concern for you then:
Don't judge catalogs by their size. Over the years, Adobe has made changes to how catalogs store data, plus some catalogs may have been "optimized" while other may not have been, making comparing the sizes a meaningless way to understand what is in the catalog.
You want to judge catalogs by what photos they contain. How can you do that? You open the catalogs and look at the photos they contain with your own eyes. Sort the photos by capture date and see what the earliest and latest photos are. Look at what is in there.

You won't be able to open all these catalogs, because they are incompatible with the current version of Lightroom Classic. If you try to open such a catalog and Lightroom Classic tells you it needs to upgrade it, then you know for sure this is an old catalog.

Thank you for taking the time to guide me, to both JohanElzenga and dj_paige, it is highly appreciated!
I have now looked through all the existing catalogs. I organize my pictures in folders in Windows Explorer, naming the folders such that they appear in chronological order.
For each catalog i have noted the size of the catalog, the total number of pictures. Also the earliest and the most recent folder included under the "Pictures" folder. This information is set out in a table in Excel. A graph is included to illustrate the variation in total No. of pictures and the catalog size. See the attached file "LR Classic_Study of Catalog Contents.pdf".
Looking at the table and the second attached file "LR-Catalog-v13-3-2.pdf", my first question is this: The catalog "Lightroom Catalog-v13-3-2.lrcat" seems to contain only a few folders, while its size indicates that there should be more. I suspect that not all content is shown. Is there a way of bringing any hidden content out into the open?
If that is possible, it may well be that "Lightroom Catalog-v13-3-2.lrcat" contains the lot, and any further combination of catalogs is not required?

First, I cannot open your (or anyone's) file attachments. So if you want to provide information, make screen captures and include the screen captures by clicking on the "Insert Photos" icon.

As I stated earlier, looking at file sizes doesn't really tell you much, and can be quite misleading. So I wouldn't bother showing me your table of file sizes. When you say "seems to contain only a few folders", are you determining this via the file size, or did you actually look into the catalog with your own eyes and see what folders are in there? When you look at a catalog to see what it contains, you can go to "All Photographs", sort them by date, and then see the earliest and latest dates of the photos. You can use the filter bar to get more detail about what dates are (or are not) included in the catalog.
It also happens to people that sometimes the wrong catalog is upgraded, which can cause certain expected folders to not be in the upgraded catalog.

To dj_paige:
I am referring to the two files that you were not able to open as attachments. You find them at the top of this post.
Regarding file size - I have noted your advise not to use file size to judge catalog contents. I included it in the table only as a rough indication.
I have looked into the catalog "with my own eyes", and extracted two pieces of information from each catalog and presented that in the table of the file "LR Classic_Study of Catalog Contents.pdf:
1.) Total No. of pictures.
2.) The dates for the earliest and the latest folder of pictures.
Thanks for the tip about sorting "All photographs" on date, this will definitely be a useful tool.

Well, this is odd. There is no catalog with photos after 31AUG2024.(Maybe you haven't taken photos after 31AUG21024 and imported them into LrC)
However, by combining catalog 13-2 and catalog 13-3-2, your date range is from 2003 to 31AUG2024, with some overlap. Isn't that the combination you were looking for?

Suggestion — you won't need to do this again is you have all of your photos in one catalog from now on.

This is what I would do:
Create a new, empty catalog with a meaning full name, like "Lightroom Catalog Master", in the location you want it to be.
Use File > Import from Another Catalog to import your catalogs, one by one. If you are asked to upgrade, then choose the first Upgrade option (Discard Upgraded Catalog After Import) - you won't loose the catalog that you are importing, it just won't keep an upgaded copy.
Start with "Lightroom Catalog-v13-2.lrcat". When that is done, then import "Lightroom Catalog-v13-3.lrcat". If there are photos already in your new catalog (duplicates), they won't be imported.
Repeat with "Lightroom Catalog-v13-3-2.lrcat", then "Lightroom Catalog-v13-4.lrcat".
Continue with earlier catalogs, "Lightroom Catalog-v13.lrcat", "Lightroom Catalog-2-v13.lrcat", etc. until they are all done.
When finished, you still have all your current catalogs as they were. You might find that you have deleted or moved images over the years; locate these in your new catalog in the Library using Library > Find Missing Photos and do what ever is necessary.
It could be a big job, so good luck.

CONCLUDING SUMMARY
Based on the collected advice from dj_paige, JohanElzenga and drtonyb, I have gone through the following procedure, ending up with one master catalog for future use:
What sent me off on this "crusade" initially, was the missing folders in the then current folder, "Lightroom Catalog-v13-3-2.lrcat":
The folders appeared «out of the blue» at some stage of this process. I suspect that they were hidden under the drive D: shown in the picture above. I believe that I was misled to think that there was nothing inside that drive, and never opened it
Anyway, this «crusade» has been very useful. I am now better equipped to handle catalogs in LRC, they felt previously like a dark cloud hanging over my head. So, I am grateful to the above mentioned community experts for guiding me through this!

Glad it worked for you. Thanks for letting us know. The word crusade conjures up visions of armies of knights facing off against armies of Muslims in the 12th century, Saladin vs Richard The Lionheart. Perhaps a better word could be chosen.

Thanks, dj_paige, for this consideration. I am aware of the origin of the word crusade. I was, however, not thinking of it in the literal sense. My intention was to express the feeling I had of a venture into the unknown. I'm sorry if this could be misinterpreted.

Glad to see that you have resolved your catalog(s) issue.
Just a bit puzzled that you said you imported two catalogs into a new empty one using File>Import Pictures and Videos. Is that a mistake? That doesn't import catalogs. Did you mean File>Import from Another Catalog...?

It was File>From another Catalog. Thanks for correcting this!
