I'm looking for articles describing (or proving nonexistence) of isometric embeddings of $m$-dimensional space $\ell_q^m$ into $L_p$ and $\ell_p$ for $q,p\in[1,+\infty]$.

Since $\ell_q^m$ is finite dimensional some (not necessary isometric) embedding always exist. I'm interested in isometric ones.

Thank you for taking time.

It's not exactly addressing your question, but did you see this blog post by Leonid Kovalev? He recommends the book by Milman and Schechtman for the "real stuff". –  commenter Oct 29 '12 at 21:00
    
what does "real stuff" mean? –  no identity Oct 29 '12 at 21:02
    
I'm only quoting him. I suppose he means that the sharpest known embedding constants between finite-dimensional $\ell_p$-spaces and much more can be found there. I don't know the book, but given the reputation of its authors it's probably worth a look. // You said elsewhere that you were reading the book by Albiac-Kalton. The chapter on local theory should contain something, too. –  commenter Oct 29 '12 at 21:05
    
Thank you @commenter –  no identity Oct 29 '12 at 21:07
    
@commenter Yes using result on embedding of $\ell_q$ in $L_p$ we can get some partial progress. The case $p=\infty$ is also of small interest because every separeable space ismotrically embedded in $\ell_\infty$ and $L_\infty$. –  no identity Oct 29 '12 at 21:08
