Asymptotically efficient in-place merging:

Abstract: "Two new linear-time algorithms for in-place merging are presented. Both algorithms perform at most (1+t)m + n/2[superscript t] + o(m) element comparisons, where m and n are the sizes of the input sequences, m [<or =] n, and t=[log₂(n/m)]. The first algorithm is for unstable mergin...

Summary:Abstract: "Two new linear-time algorithms for in-place merging are presented. Both algorithms perform at most (1+t)m + n/2[superscript t] + o(m) element comparisons, where m and n are the sizes of the input sequences, m [<or =] n, and t=[log₂(n/m)]. The first algorithm is for unstable merging and it carries out no more than 4(m+n) + o(n) element moves. The second algorithm is for stable merging and it accomplishes at most 15m + 13n + o(n) moves."
