It's a problem for me, too, that I haven't completely solved yet. I have a 40-volume set of the Scott International albums plus about 30 (so far) green Scott Specialty albums. I think I may be obsessed.
With the one-country Specialty albums, I either put on one of Scott's green country labels or I print out a label from my
Brother P-Touch label maker. Lately, I've been unhappy with the green Scott country-name labels whose gold print on dark green background I find hard to read. So I've been removing them (use a hair dryer to soften the adhesive, and they pull right off) -- and I've been adding black on white P-Touch labels which -- so far over the last few months -- have not fallen off the spines of the albums. I guess we'll see.
In my 40-vol worldwide collection, I organized my Scott Internationals alphabetically since having every volume be all A-Z countries from a different era or different decade would have led to endless searching and a great deal of frustration. That leaves each volume with fewer countries -- but still often 4-8 per volume. What I've done so far is add a number sticker -- from 1-40 -- to the base of each album's spine to help me keep them in the correct order. I've uses
"vinyl number stickers" which you can easily find under that name from
Amazon. They come in different sizes in black or white. After a couple of years, these stickers have held on well.
I'm still arranging pages a little even after about 4 years, but what I could when I'm finally happy with the countries in each volume is add a list of the country names to each spine. I'd either use my P-Touch label maker to make the labels and just list them down the spine -- or print them on a separate larger label. That shouldn't be difficult. What may be difficult, though, is keeping them attached since the binder aren't smooth.
To see what works, I've experimented a little with some different glues -- Elmer's included -- to see if any glue is more "adhesive" and more likely to remain tacky for years than the others. No good results yet.
What I have found is that if I also put a clear tape-like "label protector" over a label, it stays there pretty well. Search
Amazon under
"Clear Label Protectors" for different versions of what I use. The numbers I added are circles, so I found some circular clear plastic "label protectors" a little larger than the number stickers -- and put them over the numbers. They've been on there just fine for some years now. So I imagine I could use similar clear stickers over a list of countries in each volume -- if I did that.
Or I could print out (or handwrite) the countries in each volume on a card and tape that to the binder. Maybe not the best-looking method, though.
With worldwide albums, another issue is that if you move a country to another volume, you have to change the lists of names. But I suppose removing a label and rewriting it shouldn't be too much of a problem.
I also have a Plan B for my Internationals -- no country names at all on the binders, just numbers. I could make a master list of what's in every binder, put it in a clear page protector, and post it on the bookcase where the albums are. That way, I just look at the list to see which album I want. If I need to move some pages to another volume, I'll just redo the list and print it out again. This method saves me from listing countries on the albums. I'm starting to like Plan B more and more since it only requires number stickers on the albums. I think it also makes the binders look better than all those lists of names would.
Have fun!
