Gents, thank you for attention but it looks like you did not get what I want. Or I can’t explain correctly 
I need STRATEGICALLY organize all my bookmarks in my Obsidian vault. So I need to make a decision and then just follow it.
So I ask our Guru for better solution I believe that everybody use it so I want to do it right from the start.
As I see - there are two variants:
1 - BIG bookmark note with Headings…all other notes just link to the appropriate Heading of the Bookmark note. Like I write an article about Pencil - so all sources, useful URLs etc I put into Bookmarks.md under Heading - Pencil. So anytime I could refer to it.
2 - Each note has it’s own List of sources, urls, names of software, blogs etc at the end (for example). But I have to make big table of contents to compile everything together… In this case I think I will have a lot of duplicates.
