Any Reason To Keep Older Scott Catalogs?

So I've been working from a full set of Scott catalogs from 2019 and am in the process of updating to current ones. Besides having them marked as to which stamps I have and will most likely try to transfer the marks to the new catalogs, is there any reason to keep the olde ones?? i.e., any info in them thats not included in the newer catalogs?

Also, I've read and head that for the later catalogs ( not sure what year this started ) , Scott split out info from the Specialized catalog into smaller separate publications. But for the 2025 issue Specialized I see this:




Included is the stamp identifier and values. I had thought these were not included?? Can anyone tell me what might be the difference between by 2019 one and the 2025 issue - C25US? Not seeing in the 2025 ( from my image above ) - Air Post, Plate Blocks, FDC's, Essays & Proofs, Computer Vended, Telegraphs & UN.

Additionally I am confused because the place where I ordered from told me originally things were not going to be split out but that Scott received so much flack that they put things back in?!?

so I was continuing to search and got a couple of more posts I did not see earlier. Guess the changes started 2022/3.... Also see that the images are smaller?!? Guessing im at least going to hold on the my 2019 Specialized - not so much for values , but content. I do have a 2016 Vol1 volume will go to library auction.

saw this somewhere but now cant find post. The new catalogs at least seem smaller in print even though the font size looks the same.

Your question supplies your answer. If you want to offer up as freeware or donate that would be fine, otherwise recycle.

One crafty collector I know takes his old marked up catalogs and pulls out pages by country, and takes them to shows as a checklist on what to buy. Much better than lugging 12 volumes.

Use social media (Facebook, Craig's List, Ebay) if you are content to sell the older catalogs or recycle them. I have a 2006 catalog set for my older stamps. If I need to reference a newer catalog, I use the library.

I bought a Scott Catalogue circa 1977, Vol. 1: US, UN, British Commonwealth, as I recall. it was about 10" x 7" (fit very comfortable in the hands) and had a red cover that felt almost like faux leather. Pages were thin but strong paper, and all illustrations were B&W of course. I used it for decades as a reference, mainly for my Ireland collection--very useful. I eventually updated, but I saved the old 1977 catalog. Last year, I passed it along to a US collector friend. He had a lot of fun looking at it, especially the catalog values form nearly 50 years ago. So while I generally like to travel light, in this case, I'm glad I kept the catalog for its historical interest.

I used a 1920 Scott worldwide catalog earlier today:

and a 1936 Scott US Specialized catalog:

I have a plethora of Scott, Michel, Gibbons, Minkus, Facit, Ceres, etc, etc catalogs left over from our store and two defunct local club libraries. We closed in 2017. To my surprise of all the stuff ( supplies, mounts, gauges, etc ) I have given away to the locals clubs and other collectors, the one category of items no one wants is older catalogs. Why, I have no real idea, other than the novice and general collectors do not like the bulk, and some collectors are even hestitant to use google translate and other apps which, imo, make non english catalogs a breeze to use. I am still reluctant to pitch those in decent shape away, and have the storage room. So they will probably go when I do. Even the local libraries and used charity book sales will not take them. SMH

Unless you collect very recent material, an older catalog is fine. I am still working with 2017 era Scott catalogs (back when 6 volumes).

But I also use online sites that make identification much easier (image and denomination searches). f I had a valuable stamp, I would not rely on the catalog value.

As I don't collect much material newer than 1940 or so, all my catalogs are pretty well dated (SG World Simplified from 1969....one volume(!!), 1995 Scott World set, and a U.S. Specialized and s Classics from 2018). For checklists, these work swimmingly given my collection parameters. I'd rather spend my money on stamps than on updating catalogs and if I need to figure out a valuation for older or more recent issues, I can generally get an idea of what the market is doing by perusing HipStamp, eBay, and the like.
That said, I will buy new specialized catalogs for the new research and information they contain (and as a bibliophile, some antique catalogs from around the world for the beauty of their designs and illustrations).

All good tips and suggestions. I think I have another reason, maybe, to keep the old one.....

I just noticed in my 2019 India Feudatory for Bundi, the numbers have changed in the 2025 catalog. Im not sure where or when besides making the update now that id need to know that the numbers changed, but Scott as far as I know does not keep an online record of number changes and without having all the catalogs between 2019 & 2025 I dont know where id look.

I buy old stamp catalogues (Scott, SG, Michel, Y&T, specialized) - I have been collecting them for a few years. If anyone doesn't want their old stamp catalogs I will gladly buy them and pay for shipping. There are maybe some catalogues I won't need or use, but please don't be afraid to reach out to me. Btw, just FYI, I haven't reached 50 quality posts here yet - I'm still working on reaching the mark.

I have nine old Scott catalogues dating from 1900 to 1949. They are interesting to read. I take one out occasionally and read through it. I'll buy older ones when I find them at antique shops, flea markets etc.

One of my collecting friends has been looking for OLD catalogs since he started the hobby. He has a few from 1880 time frame as well as an almost complete set from 1889 to 1917 and from 1920 to the 50's. Not too sure what he does with them and he admitted to me he doesn't know why he keeps them!! He has boxes of them all over his house with no shelving to properly set them up.

Rick2,
People save old catalogs for a variety of reasons.
Some of us simply collect philatelic literature like any collection.
Some of us use them for documenting when additions, deletions, renumberings, and other changes to listings were made (Note the two links I posted here on Oct 14).
Also for price/value histories, and more recently, for when sections are split-off into separate publications.
My Scott run is not nearly complete, but I am about half way there.

Add: Here are two additional threads addressing some of the historic Scott numbering changes. The first touching on the 1930 and 1940 changes:
