I'd like to build a non-copyrighted list of journals/serials (anything with an ISSN, basically) - including their ISSNs, full titles and abbreviated titles.
As a start, every item needs an identifier. The ISSN International Centre assigns ISSNs to publications that request them, but the data file listing all the ISSN:serial title mappings is copyrighted, expensive and not redistributable (it also uses sentence case for journal titles, which means some information gets lost).
As each publication can have multiple ISSNs - one for each medium in which it is distributed (for example, the online version of a publication can have a different ISSN to the print version) - a pan-ISSN identifier is required to link all the ISSNs together, so the ISSN-L was introduced.
The table that maps ISSNs to ISSNLs can be downloaded from issn.org after filling in a form requesting access. In the latest table, there are 1,614,355 unique ISSNs, mapped to 1,552,542 unique ISSNLs.
This ISSNL:ISSN mapping table, like all the information published by the ISSN Internation Centre, is protected by sui generis database rights, which last, according to Wikipedia, for 15 years from the last substantial update.
The databases appearing on or accessible from the website "the ISSN International Centre" are the exclusive property of CIEPS and are protected under the provisions of the law of 1st July 1998 implementing in the Intellectual Property Code the European Directive of 11 March 1996 on the legal protection of databases. Any performance, whether total or partial, of this site by any company whatsoever, without the express authorization of the CIEPS is strictly forbidden and shall constitute an infringement sanctioned such as Intellectual Property Code.ISSN International Centre, Legal Notice, Section 3
(note, incidentally, that I'm already in conflict with section 3 of the legal notice: "Users and visitors cannot place a hyperlink to this website without the CIEPS' express and prior authorization."…)
The full database itself may be copyrighted, but (I believe) the individual facts within it shouldn't be. In which case, the best non-copyrighted source for the journal title, ISSN and ISSN-L of each serial is probably the publishers themselves, and as many publishers make their metadata through an OAI interface it may be possible to extract a fair amount of serials information from those sources. ScientificCommons, for example, harvests articles from OAI repositories, so may be able to aggregate useful title and ISSN information.
Existing, non-free sources
Other sources of Journal/ISSN information
- 300,000 serials in Ulrich's (JSON interface somewhere?)
- SerialsSolutions Summon (title list as PDF)
- 13,000 journals in EBSCO "Academic Search Complete"
- 91,000 journals in WorldCat Local
- 17,000 journals in Thomson Reuters Master Journal List
- 27,000 journals in CrossRef
- 12,500 journals archived by Portico
- 9,000 journals participating in LOCKSS
- 3,330 journals in ScienceDirect
- Journal lists by subject in Bing Academic Search
- Search journals in the CAS Source Index (copyrighted by the ACS)
It would be nice if Freebase could serve as a central repository for this information, but there are only 4,321 journals in Freebase so far.
Once we have the list of ISSNs and journal titles, we also need the corresponding journal title abbreviations, for use when generating bibliographies. There are lists of journal title abbreviations available for import into EndNote. Sadly, there are several different abbreviation styles (ISO, MEDLINE, BIOSIS, CASSI, etc).
- The ISSN International Centre maintains the list of Title Word Abbreviations which corresponds to the ISO 4 standard (available from the ISO store for ~£50), which describes the rules for abbreviating title words and titles of publications. The list of Title Word Abbreviations is available online as HTML.
- The NLM uses the list of Title Word Abbreviations to abbreviate periodical titles.
- The NCBI provides a less-comprehensive list of abbreviations for commonly-used English words in journal titles.
- The jabbrv LaTeX package abbreviates journal titles using the list of Title Word Abbreviations.
- The JAbbr service built a list of abbreviated serial titles from the Cornell library catalog of MARC records, and provides abbreviation → full title mapping as a JSON and HTML web service (source code provided). Article in Code4Lib Journal.
- The NLM Catalog is searchable using a journal title abbreviation, but uses sentence case for full titles.
- The NLM Catalog is also searchable by various ISSNs.
- Web of Science has a list of journal title abbreviations.
- A large list of Journal Abbreviation Sources.
