The update of Teseo data brings new and significant findings. It has been detected that the actual number of doctoral theses registered in the new compilation is 196,442, compared to the 132,378 obtained during the initial analysis. The error causing the incomplete collection has also been identified: a several-hour interruption occurred during the process due to a failure in the Internet connection service. For these reasons, all information published on this portal has been updated. I therefore wish to apologize to the scientific community and provide the new, much more accurate data, which paint a different picture of the doctoral theses sector in Spain.
Changes in the data analysis
The Teseo database contains 196,442 registered doctoral theses accessible through 1,190,508 identifiers, of which 994,066 are duplicates. The data obtained in the initial analysis up to the year 2004 are correct. However, information for the period 2004 to 2015 was not fully collected, resulting in an apparent decline in the number of registered doctoral theses that is not as pronounced in reality. In fact, the highest number of registered works occurred in 2014, with a total of 9,798 entries. Read the full analysis in the updated article «Teseo Database. Initial Data».
Changes in Teseo downloads
The increase in the number of records in the TESEO database has led to changes in the files prepared for export in SQL format, available from the Sourceforge.net project repository [https://sourceforge.net/projects/teseo-database/]. A new version has been created, corresponding to version 1.1 dated [2015-11-14]. Read the article «Catalog of Spanish Doctoral Theses TESEO Available for Download».
Next Steps
Based on the most accurate information obtained from this second analysis of TESEO, I wish to announce the forthcoming publication of new analyses currently underway. In the coming days, a chronological analysis of doctoral theses by university and discipline or field of study will be published. This will allow us to identify which areas of science are most prolific and how their temporal distribution varies across Spanish universities.
