Leonid Libkin authored 5 books and close to 200 technical papers, including 10 papers in Journal of the ACM, which, according to its charter covers "the most significant work on principles of computer science. To be accepted, a paper must be judged to be truly outstanding in its field." 
He has had over 30 papers in ACM PODS, the top conference in foundations of data management. He published extensively in LICS, the top conference on logic in computer science, in ACM Transactions on Database Systems and on Computational Languages, and many other highly ranked conferences and journals including SICOMP, JCSS, TCS, Information & Computation, LMCS, ICDT, SIGMOD, STACS, ICALP.\\

Many of his papers, particularly on expressiveness of real life languages, on embedded finite models, on static analysis of XML, on normalization, on data exchange, on locality of logics became standard references, and are often used in courses. According to Google scholar, his papers gathered over 7400 citations, and his h-index is 44.
