Hi, peeps! I was wondering what's the source of the equipment descriptions?

Besides the ones included in the PHB why are there listed other items? I mean they are sourced from other places, I know. But why can I see them?

For example Crampons or Airships

Thanks

Do you own the books they are sourced from? Probably that’s the issue. Quickly, it looks like crampons are in frostmaiden and airships are in storm king and eberron. 

Alternately, a likely explanation could be that you have content sharing access via a campaign + someone's subscription

No. I have MM, PHB, DMG, XGTE and EGTW. I'm the only one with a subscription and I'm only on one campaign.

I mean it's cool to have, but that's precisely what I want to know, where is this from, to look into more content like that

Another example is Stakes (Wooden). But for those I have it figure out. They come from the Monster Hunter's Pack which in turn is mentioned in the Haunted One background which is part of the free Curse of Strahd character options.

Dragon's Blood is from Eberron, for which I don't have access neither.

Again, It's cool to have acess to that kind of thing, but Dragon's Blood is interesting! I'd like to know where it is from so I can consult further material

mundane equipment isn't locked like most other content.  If you log out, you can still see descriptions of all the various equipment items...doesn't work that way for magic items.
