From: "Blobaum, Paul" <[log in to unmask]> Date: Thu, 20 Feb 2014 01:00:28 +0000 PubMed is not an index technically speaking... It is a citation management platform for PubMed Central plus citations indexed for MEDLINE. Citations are provided by publishers for the purposes of linking to prepub articles, PubMed Central contents, or for historical purpsoes, many are not critically reviewed with MEDLINE indexing. The criteria for reposition of journals in PubMed Central is different than MEDLINE inclusion criteria. Your comments are well taken, but it is not uncommon for association publishers to limit access to membership for current journal issues and trade magazines. I found out the hard way with getting a library subscription to the Journal of Addictions Nursing. Even though my library paid for a direct subscription, there was an 18 month embargo of current articles, limited to association members. Professional associations have every right to do this but I do not agree with it. Another example is the Journal of the Medical Library Association, which is deposited in PubMed Central. The current issue is available to members of the MLA only, then the immediate past issue and all archives are available in PubMed Central. Science is published by the American Association for the Advancement of Science.

Here is an example: Jinek, Martin. (2014). Structures of Cas9 Endonucleases Reveal RNA-Mediated Conformational Activation. Science [0036-8075]. This article was posted on Science Web site on Feb 6, 2014, as a pre-publication article, and it has been indexed by PubMed. My library has current online subscription to Science, and has no problem accessing other regular articles. But as of today, access to this article requires payment. Publishers should stop this practice. It confuses both users and librarians, especially when they try to get the article from an index and OpenURL link resolver. --- Xiaotian Chen Electronic Services Librarian Bradley University http://hilltop.bradley.edu/~chen/
