English-language bookstores?

Sterling Books (Wolvengracht 38 Fossé aux Loups) and Waterstones ( Boulevard Adolphe Maxlaan 71-75)

The fnac in City2 at the top floor has a really good range of English books.

It can make a difference when it comes to prices...

Always buy English books on line- the price in the shops in Brussels is extremely high.

Always buy everything online if you can, not just books.
Still, some of us are old fashioned and enjoy the satisfaction of purchasing when out and about.

The regular sales around May/June are good for stocking up cheaply (churches, "international" schools, etc.). That does me for the year, and online for specifics where I have to shell out full whack.

I also love browsing books in real, although I then often end up buying online. Filigranes (www.filigranes.be) is my favorite in Brussels. Their English section is not very large, but they are also a cafe so you can sit down to read without buying. The English books are in the basement (turn to right right after the entrance).

Pel Mel on Chausee de Waterloo ( between Bascule and Ma Compagne opposite Delhaize) has a large and well organised English book section;, fiction and non fiction.

The Oxfam bookshops are also very good, I use the one on Chaussee d'Ixelles near Flagey and that on on rue Vanderkindere.
