INSIDE or OUTSIDE, Bulbs in Containers over Winter.

I keep my potted bulbs under cover to keep them dry. They can cope with the cold but not the wet. You only need to water them once when planted up, then when new shoots are showing. Take them outside when weather conditions are more favourable and they are about to flower. I'm in SW England so much milder than Glasgow!

I'd keep them all outside. You can shelter them against a wall if you want, to prevent any waterlogging, but it's really just tulips that need it. 
Mine all just sit out in their final positions 

You might find anemones are a bit iffy - I'm assuming you mean the de Caen types? They need quite specific conditions - they rarely do much for me as i can't provide them with that, although they might be better in pots as you can move them.

I don't think it matters too much where you keep them - wherever is more convenient for you. They would certainly need to be moved out of the garage as soon as green shoots start showing so you'd have to keep an eye on them and you may find that they start to do that earlier if they are inside. Certainly if you've squirrels around, it would be safer.  On the other hand, tulips particularly need a period of cold (I forget why) so in or out may depend on your weather conditions up in Glasgow.

Monty Don suggested a coldframe with the sides open - so shelter from wet and snow, and that's what I do. I am in the far south, the Isle of Wight, so extreme cold isn't much of a problem. I imagine that bulbs planted in the ground freeze, however, so wet is the real issue. I have never tried anemones, either.

Don't put them in the garage @Andrew.D.P. Outside, some shelter for the tulips if you're concerned about waterlogging, but if you've planted them correctly, and have them on some small supports, they will be fine against a house wall. They won't last more than a year or two anyway.
They should be planted too deep for squirrels too. The only ones which are likely to be dug up are the anemones. Chicken wire foxed over the top sorts that.

Put them in the lee of a fence or wall - rain and wet will cause more issues than cold per se. A house wall will give some thermal protection if minus double-digit temperatures are expected though.

Hello, Andrew.
I'm in a, currently, very wet North Yorkshire, and am expecting a cold winter. I have planted a large range of bulbs too. I'm keeping the majority of the tulips in  a closed cold frame (there are enough little gaps in it to allow airflow -Ref: Monty Don)
I have a selection of crocus, dwarf iris and dwarf narcissus in my cold greenhouse.

As shoots appear in any of the pots I stand them outside, sheltered against a South facing wall.

All pots are topped with grit and covered with chicken wire as squirrels are a problem in my garden.

Hope this helps you decide what to do.

I have species tulips, daffodils, crocuses, alliums and dwarf gladioli shortly to be potted up. They are going against a sunless north wall, sheltered by the roof overhang.

My winter days are often dry and sunny but with massive temperature drops and heavy frosts overnight, so I don’t want them getting too warm during the day and be tempted to poke tender wee shoots out too early..
