  The Yangian double $\text{DY}_{\hbar}(\mathfrak{g}_N)$ is introduced for the
classical types of $\mathfrak{g}_N=\mathfrak{o}_{2n+1}$, $\mathfrak{sp}_{2n}$,
$\mathfrak{o}_{2n}$. Via the Gauss decomposition of the generator matrix, the
Yangian double is given the Drinfeld presentation. In addition, bosonization of
level $1$ realizations for the Yangian double
$\text{DY}_{\hbar}(\mathfrak{g}_N)$ of non-simply-laced types are explicitly
constructed.
