In the foreign Languages Bookstore are to be found books in various languages.

这是一个倒装句。恢复正常语序为:

Books in various languages are to be found in the Foreign Language Bookstore.

这是be to do结构表示将来时间。这种结构表示安排、计划、命令、注定会在将来发生的事件。你可以近似地理解为will do. are to be found大约等于will be found.

be to do是半情态动词或准情态动词(semi-modal),通常表示将来时间(计划、指示、要求等)。但当不定式为被动语态时,也常用于表示多种其它的情态意义,可相当于can, should, have to等。例如(1) Nowadays no such concentrations of geese are to be found(=can be found) on Rockliffe Marsh. (2)What is to be done (=should be done 或has to be done) then? We must find some solution.  因此,在你提到的In the Foreign Languages Bookstore are to be found books in various languages一句中,are to be found相当于can be found,从而与are found有所区别。
