Adjaye Associates ( pictured above), MAKE and Glenn Howells Architects ( both pictured below) have each produced architectural concepts - unveiled earlier this week - for a city-centre site.
Called the 'Library of Birmingham Knowledge Centre', the development will sit between Baskerville House and the Birmingham Repertory Theatre in the city centre.
Councillor Mike Whitby said: 'The new development will be a social, creative and cultural destination - open, welcoming and accessible to all citizens.'
The proposals will also house a new Archive and Heritage Centre, to accommodate the city's collections of local history and photography.
Birmingham City Council's cabinet will meet at the beginning of next week to discuss the designs.
A spokesperson for Richard Rogers Partnership, whose proposals for a library at Birmingham Eastside were dropped early last year, said: 'We continue to believe that our original scheme for the Library of Birmingham at Eastside remains the best approach.
'However, it's now a matter for the council to decide.'
