01kipper: The docs are there, but you have to download them separately. Go to your gog Account > Library > Silent Service 1+2. They are in the "bonus content" section.
estevanalfredo: thank you for responding. I went....again, to the library. it said I was downloading the documentation, maps, clue books.....great, until I right clicked on it. all it does is take me straight into the game/ I went to the library first, yes. and there was no place with the exact words...bonus anything. so I did as I already said & it just took me...straight into the game. sounds repetitious, huh? boy-wee, it is. and nowhere is the manual. there's lots of great games here. I want them, but not having the manual is like buying a soul, without the body. nothing there. .......sigh.......thank you, again.
GOG has changed their layout since I did that screenshot, but if you've found the documentation to download then I think your problem is that you actually *have* downloaded the manuals, but you just can't find them on your computer.
If you are using the gog.com webpage, the manuals will be downloaded to whatever is the default download location you've set for your browser.
If you are using GOG Galaxy, then it has its own location. You can find this by clicking on the little gear in the lower-left hand portion of the Galaxy window (see screenshot1 attached), then near the bottom of the window that appears, look where it says "Download game extras to:" (see screenshot 2 attached).
(*Note that I'm on a Mac, so your version of Galaxy may or may not differ in minor or not-so-minor ways from the screenshots)
ETA: The names of the actual files for the manuals (in case it's easier for you to just do a search of your computer for the files) are:
ss1_manual.zip
ss2_manual_english.zip
