BibTeX key generation was improved and consolidated and every paper on INSPIRE is now guaranteed to have a BibTeX key. BibTeX keys allow cross referencing of bibliographic information in LaTeX documents. The keys are part of the BibTeX output format and are generated as follows: <family name of first author>:<year>< 3 random letters>

For collaboration papers without a list of authors upon ingestion to INSPIRE, the TeX key will be generated based on the collaboration name. Records with existing SPIRES keys are not affected by this and those keys will remain functional.

The large collaborations at the LHC have an unusual intermediate form of publication: the conference note.  These are significant results prepared by the collaboration for major international conferences (not to be confused with proceedings written by a conference attendee).  They are  heavily peer-reviewed within the collaboration, signed by the collaboration as a whole, and often precede submission to a journal.  Moreover, these conference notes typically provide more detail than the documents submitted for publication, which makes them particularly valuable to anyone following the research closely.

However, finding these conference notes has confounded almost everyone that has looked for them.  They are “catalogued” in a maze of wiki pages, plain HTML pages, and various categories in the CERN document server (CDS).  While CDS is based on the same underlying Invenio technology, it lacks much of the functionality that INSPIRE offers.  In particular, there has been no way to easily navigate references, track citations, or generate bibliographic information.

This situation improved dramatically when both ATLAS and CMS agreed to put these conference notes into INSPIRE.  There are already more than 800 conference notes indexed, with many more to come!

For example, you can find the ATLAS conference notes with
find r atlas-conf-*
and the CMS Physics Analysis Summaries (PAS) with
find r cms-pas-*

Now, I can easily track citations to a recent conference note on the Higgs decaying to photons; perform a full text search for the word “asymptotic“; and see which ATLAS conference notes have been cited by CERN theorist Christophe Grojean.

As an author of several of these conference notes, I am particularly excited about the ability to generate standard bibliography entries.  For example, I can easily export a .bib file for all the 2012 ATLAS conference notes.  This will be a huge time savings for the collaborations and a great example of the impact an excellent literature database can have!

Once more, we extended the information we provide on our author profile pages on INSPIRE. You can now find subject categories among other information such as affiliations and co-authors. Furthermore, we provide you with a graph showing the numbers of publications per year. You might need to clear your browser cache to see the graph. As it takes a lot of processing to calculate this information, we precompute them regularly for your convenience. In the bottom right corner of the page, you can find the date the page has been generated and a link to recompute it to get the most current information on an author.

To access these author profile pages and see our novelties, just click on an author name the next time you do a search on INSPIRE. If you think there’s still information missing on these pages or have other comments and questions on author pages, don’t hesitate to contact us at

Datasets from HepData are now integrated into INSPIRE. HepData is a data repository hosted at Durham University which aggregates data extracted from publications in HEP and other datasets made available by the experiments. The data is presented in tables and available as data files for further reuse (plain format on INSPIRE; more formats are available on HepData). With the integration of HepData into INSPIRE, you can access data sets from HepData directly when browsing bibliographical records. If a record on INSPIRE has data from HepData attached, a corresponding tab is displayed next to the references and citation tabs. About 50,000 data files attached to about 7,000 records are available which are stored as regular records in INSPIRE. Datasets from 2012 e.g. can be found here.

Recently we reprocessed the citations of articles in the Journal of Physics. For historical reasons, each letter series of the Journal of Physics (A through G) was treated in SPIRES, and then INSPIRE, as a separate journal. For all the other journals in INSPIRE each letter series is simply treated as a volume of a single journal (for example, Nuclear Physics, Physical Review and Physics Letters). Because special exceptions had to be made in the database for how we handled the Journal of Physics, it was difficult to guarantee that searches, citation counts and even the display of the publication note always worked correctly.  INSPIRE contains almost 13,000 J.Phys. articles with over 100,000 citations. The re-indexing was completed a while ago but during clean-up you may have noticed a temporary fluctuation in the citation counts. However, everything is fixed now and our entries are much more consistent. In the process we saw citations to J.Phys. articles rise by several thousand.

As we consolidate the move from SPIRES to INSPIRE we will continue to examine things that, though they once made sense in SPIRES, no longer need to be done the same way. One particularly important issue is the eprint number. In SPIRES, depending on where in the record it was stored, an eprint number could be written: hep-th/9711200, hep-th 9711200, hepth-9711200 or even arXiv:hep-th/9711200. Cleaning up this is sure to net some long-hidden citations!

Following our users’ request to extend the historical content of INSPIRE, we now provide full text PDFs of contributions to the International Conferences on High-Energy Accelerators (HEACC). Conference proceedings are a cornerstone of communication for the Accelerator Physics community, (as preprints are for the HEP community) and these proceedings are very valuable, as HEACC was the first important accelerator conference series. In total, 18 conferences took place – the first one in 1956 at CERN and the last one in 2001 in Tsukuba in Japan. The proceedings have been scanned and are searchable. Unfortunately, the contributions from the 11th (in Geneva in 1980) and the 15th (in Hamburg in 1992) conference cannot be made available, except for preprints we already have in INSPIRE, as the copyright for these is owned by the publishers. The 2001 contributions are only available in digital form. Unfortunately, the links to the conference homepage are broken but we will try to get in touch with the editors to make these contributions available. The conferences can be found in the conference database with the search find series HEACC. As part of each conference entry, you will find a link that leads you to a list of the contributions.

In addition to the conference proceedings, we have also scanned the Catalogues of High-Energy Accelerators published in conjunction with some of the HEACC conferences.

If you or your colleagues happen to have an electronic version of historical material that is listed on INSPIRE, we are happy to make it available. For this or other comments, just let us know at

A few weeks ago, we pointed out that our RSS feed is a great tool for keeping you up to date, e.g. with the latest citations to your papers.

We’ve now improved our RSS feed so that more information about papers is shown in your RSS reader. From now on, in addition to title, first author and abstract, we’ll include arXiv and report numbers as well as publication information. RSS feeds are also available for the other collections on INSPIRE. So you can subscribe to the Jobs RSS feed and get new job posts conveniently in your RSS reader or stay updated about conferences via the Conference RSS feed. You can customise these feeds by searching and subscribing to the RSS feed at the bottom of the search result page.

Let us know how you like our new RSS feed and tell us if you’re still missing information at

Following many requests for more citation metrics, we have now introduced a second page of the Citesummary on INSPIRE where you can find additional columns excluding self-cites and citations to the Review of Particle Physics. You can access this extended Citesummary page via a link at the bottom of the first Citesummary page. Furthermore, we have provided some more detailed explanations of the various citation metrics; you can find them here or via a link on the Citesummary page.

Try the new metrics and tell us how you like them or if you would like some additional metrics at  
We are working on expanding our horizons in regard to citation counts. In addition to the SPIRES tradition of tracking citations to arXiv eprints and published journal articles, we are now starting to track citations to report numbers and conference proceedings, for example
This is a complex task and will take a bit longer. We will be able to offer a better service of citation analysis and interlinking to and from additional material, such as unpublished papers which did not appear on arXiv, theses and experimental notes.

As this work is ongoing you might be interested in the current citation stats of INSPIRE. We can currently track over 700,000 citeable papers out of 960,000 records overall. Of these 0.06% have over 1,000 citations, 0.24% have over 500 citations and 3.3% have over 100 citations.

Interested in more stats? Check here! Interested in searching for highly cited papers? Just use topcite, e.g. find topcite 5000+ or combine it with another search parameter, e.g. find t top quark and topcite 1000+ 

By the way – our algorithms are not perfect, yet, and can miss citations especially when figures or tables appear in the middle of reference lists, so you can help us by correcting references and citations yourself on INSPIRE. For details, please see: Please note that we’re a bit slow at the moment as we’re still completing the back office transition to INSPIRE, so it may take a few weeks for us to process your corrections but rest assured we will get to them.

Citations are of interest to the HEP community as a way of finding new papers on a topic of interest. It is therefore natural to want to find the latest citations of your own papers in order to learn of the latest developments in your field. In SPIRES this was almost impossible to do, as you had to look for new citations of each of your papers. INSPIRE is more sophisticated and allows you to do second-order searches that let you find papers citing a particular set of papers, for example those written by an author of interest: find refersto author e.witten.1 or in Invenio form refersto:author:e.witten.1

Every INSPIRE search has a link at the bottom that enables you to track the result in an RSS feed. You can then get daily RSS updates through, e.g. Google Reader or the built-in RSS readers of Internet Explorer and Firefox.  Doing this, you’ll be able to easily keep track of new citations to an author as they appear. As an aside, note that we have used the INSPIRE author identity, E.Witten.1, rather than just a name to make sure the search is unique.

This will work for searches beyond “author”. For example you could find the papers citing work done by your institution: find refersto aff “princeton u.” and then narrow that down to only citations of your institution by another institution: find refersto aff “princeton u.” and af oxford u. You basically have the full power of INSPIRE searching at your disposal.
