We are very excited and proud to announce that in July 2010 the Chinese Journal of Lung Cancer(CJLC) has been selected by the National Library of Medicine (NLM) to be indexed in Medline/Index Medicus, the world's most important biomedical bibliographical database. NLM uses an advisory committee, the Literature Selection Technical Review Committee, composed of authorities knowledgeable in the field of biomedicine, such as physicians, researchers, educators, editors, health science librarians, and historians, to review and recommend the journal titles NLM should index. Only 15-20% of medical journals are selected at each session for inclusion in Medline, and even fewer journals in Chinese have been selected for indexing so far. The Committee recently completed a review of journals for possible inclusion in the National Library of Medicine's database systems and decided to select the "Chinese Journal of Lung Cancer" for indexing and inclusion in Index Medicus and Medline. In China, Chinese Journal of Lung Cancer is the 3^rd journal indexed by Medline/Pubmed, following Chinese Journal of Cancer(Guangzhou) and Chinese Journal of Oncology(Beijing). On behalf of the editorial board, I would like to express our sincere appreciation to you for the vigorous support.

Chinese Journal of Lung Cancer was launched in July, 1998 in the First Hospital affiliated to West China University of Medical Science, and moved into Tianjin Medical University General Hospital in 2007. Since the inaugural issue, we have dedicated to build good reputation and to improve its quality for Chinese Journal of Lung Cancer. Until now, Chinese Journal of Lung Cancer has been indexed by PUBMED/MEDLINE, DOAJ, CAB Abstract, CINAHL, Global Health, EMBASE/SCOPUS, Chemical Abstracts (CA), Chinese Biological Abstracts, CNKI, CSCI, etc.

PubMed is a free database access to MEDLINE and PreMED-LINE database established by National Center for Biotechnology (NCBI). Medline is the most important bibliographic abstracts database in the United States National Library of Medicine, involving clinical medicine, nursing, dentistry, veterinary medicine, health care and basic medicine. It covers more than 4 000 biomedical journals in over 70 countries and regions and has more than 1000 000 pieces of bibliographic abstracts currently.

This approval, is a clear evidence that manuscripts published in this journal bear a significant scientific value and will assure that they remain as a lasting treasure for the scientific community. I believe that under the great support of members of the editorial board, our journal will pioneer to provide high-quality service to all professionals dedicated to lung cancer.
