A DOI ("digital object identifier") is a unique identification code that allows an article to be easily tracked by many different archival and research programs on the Internet. Every article that is accepted for publication in an APS Journal is assigned a DOI number. It the copyeditor's responsibility to make sure that this number is formed correctly.
Here is a sample DOI:
It can be broken down into three distinct parts.
The first 6 digits are the publisher's code. The publisher's code for APS is "10.1152", and is the same for all APS journals. The publisher's code is always followed by a forward slash.
The second part of the DOI is a string of alphabetic characters; this is the journal abbreviation. The journal abbreviation is determined by which journal the article was published in. Abbreviations for all APS journals are as follows:
AJP - Cell Physiology ajpcell AJP - Endocrinology and Metabolism ajpendo AJP - Gastrointestinal and Liver Physiology ajpgi AJP - Heart and Circulatory Physiology ajpheart AJP - Lung Cellular and Molecular Physiology ajplung AJP - Regulatory, Integrative and Comparative Physiology ajpregu AJP - Renal Physiology ajprenal Journal of Applied Physiology japplphysiol Journal of Neurophysiology jn Advances in Physiology Education advan News in Physiological Science nips Physiological Reviews physrev Physiological Genomics physiolgenomics
The journal abbreviation is always followed by a period.
The last nine digits of the DOI is the article number. In almost all cases, this number is generated by taking the manuscript number assigned by the peer review department and appending the year of submission. However, it is very important to remember that once a DOI number is assigned, it is not "connected" to the manuscript number or year of submission in any way. If an article's manuscript number or year of submission were to be altered for some reason after the DOI is assigned, or if the DOI is generated using the wrong manuscript number or year of submission, the DOI would not be changed to reflect the "correct" data; it is now its own number and cannot be changed.
Once assigned, a DOI number can never be changed, even if it does not reflect the proper format for generating DOIs.
The article number of a DOI must always contain nine digits — five in front of the decimal point and four following. If the article's manuscript number contains less than five digits, leading zeroes must be added to "pad it out".
Always double-check an article's DOI number against its listing in Articles in PresS, if possible. If you notice a discrepancy between the DOI given in the manuscript and the DOI listed in AiPS, or a discrepancy between the last part of the DOI and the manuscript number or year of submission, alert your journal supervisor.
The DOI number is denoted by the «doi» code at copyediting stage. This code is automatically generated when you fill out the header information at the beginning of copyediting, but always double-check to make sure it has been formed correctly.
The DOI number also appears in the blibliographic information at the beginning of the abstract. Always check to make sure the DOI in the abstract matches the DOI in the manuscript's header information.
