Could someone please decide if the query syntax of these tables is correct?

CREATE PROCEDURE usp_ConsultarLibro  
@id_Libro char(3)  
as  
Select  
IdLibro,   
Titulo,  
NomApe_Autor,  
Nombre_Categoria,   
Nombre_Editorial,  
Nombre_Idioma,  
Año_Lanz  
FROM  LIBRO L  
INNER JOIN AUTOR A ON L.IdAutor = A.IdAutor  
INNER JOIN CATEGORIA C ON L.IdCategoria = C.IdCategoria  
INNER JOIN EDITORIAL E ON L.IdEditorial = E.IdEditorial  
INNER JOIN IDIOMA I ON L.IdIdioma = I.IdIdioma  
where IdLibro=@id_Libro  
GO  

Is it necessary to put the abbreviations before the names of the fields?
