"As long as" you stick at the modern stuff, yeah. I've never read none of it. Read the paper or something where you can learn proper English without all the rubbish bits.

My unscientific feeling is that using the word of assemble usually when you do for a particular purpose.

"She had assembled a collection of her favourite songs."is a good case

put together means to construct; create: put together a new bookcase; put together a tax package.
