i do that too, any aesthetically different items i like to keep

In my house in Anvil I kept one of everything in the basemant. Each crate/chest had a different type of loot Weapons, armour, ingredients ect..

After a few days of playing, I can say with confidence that troll skulls are my collector's item in this game.

I am an ingrediant collector, and I love cooking stews, so ya i am a stuff collector.. Plates, bowls and cups not so much... I have been grabbing lotsa books recently for my bookshelves thou.. Now that I have a house.. Its kinda cool to see books on my bookshelves, meh I dunno I might be a lil ate up.. think its cool to collect stuff, for alchemy and mix em together...

So far, I have been a very avid book collector. Especially books about races and monsters and I often fill my book shelves. Also, I have a habit to not loot Dwemer ruins... Except for armour/weapons, I take those.

absolutely anything thats significant in anyway i usually keep
like cicero's journals and anything that reminds me of a quest honestly

I will always keep any unique weapons or armor I find, and in addition to that well, I actually keep everything that crosses my path. Haha. I have so many full chests, bookshelves, nightstands, etc in my house it's not even funny. I'll keep pots for that rare occation I need a pick-me-up mid battle, all my ingredients for that occasion I feel like burning through all of them at my apothecary table, books! I'm definitely a big book collector. I nab every book I can and add it to my collection. The only things I freely sell I would have to say would be the base armor/weapons that have no enchants or anything on them. If it's just a regular "Steel Iron Helm" or whatever, I'll sell that, knowing I can come across another (or make another) fairly easily. I generally don't keep knick knacks either. My house came furnished with enough junk. The first day I had my house, I had some junk on me I decided to add to the place to give it my touch. I arranged steins and glasses on the table, a stack of plates in the storage room, a jug, a bowl under a table near the cook pit, etc. and the first time I leave and come back, all the unique items look like they exploded all over my entire house. That was enough, no more extra novelty crap. Haha.

I'm usually a pack rat as well but this time around I will try to only take things that my character would take and be able to carry in real life.

Some people call it junk, I call it treasure

I collect books!

In Morrowind I collected candles, and am quite disappointed we can' tpick them up again....

I like this guy. Which kind of books? Any or do you have a selection criteria?

My character is a Dark Elf and so I collect all Elven weapons, armour, books, etc. I can, practically anything elven, currently they're in a chest of their own although when I get a bigger house they're going to be in their own room as a museum.

Yeah, sorta like this..

I am!
But right now I am trying not to grab anything only the stuff to sell, until they patch the memory leak, its such a pain to stop myself from collecting all that Misc stuff D:

Like a couple of other posters here, I'm all about the books.

I spend hrs every day jes reading them... then I steal em... get rid of the garbage on the shelves in my house and put em there.

Books. Every damned book I see I must put on display, doesn't matter what (waiting for Book Jackets Skyrim!). I also like to collect armor/weapons, ores/ingots, clutter, and shiny things such as gemstones and soul gems.

Oooh yes books! Love books!
