IPNI statistics

View figures for: 2009 | 2008 | 2007 | 2006 | 2005 | 2004

Getting good statistics out of IPNI is currently difficult due to limitations of the data.

However, from 2004 onwards we are reasonably confident that we can publish useful figures on the number of new names published, and the number of new names added to the database

Note that it takes time for names which have been published to appear in IPNI, especially if they were published in obscure journals. Therefore the figures for names published in a year should be considered provisional until at least two years have passed. We will try to keep these figures updated on a monthly basis so that as names are included in IPNI these figures will be revised upwards.

NEW Dec 09. We are now also displaying here the number of changes that are made to IPNI records each month. The data is actively curated and changes to existing records are made every day. These changes may be corrections, standardisations or enhancements of information and each one improves the quality and value of the data. You can track the changes a record has undergone by clicking on the 'View Record history' link in detail view and comparing the previous versions. It is important to be aware that the IPNI data is not static and that if you use downloaded data it is likely to become out of date extremely quickly.
