Very tall slim bookcase

[MightyMeerkat]

Any recommendations please?

Classic Ikea Billy! 40cm wide, 28 deep about 200 tall, can add another top unit too. Super reasonable price.

What about this www.quatropi.com/quatropi-tembie-tall-bookcase-display-cabinet-rich-walnut-grey.html

or this? www.wayfair.co.uk/furniture/pdp/mercury-row-cowans-bookcase-dey2582.html

By slim do you mean side to side (narrow) or back to front (shallow)?

If you want very shallow this maybe?
