With a little delay, SCImago Journal & Country Rank has released a new update to incorporate the new data coming from March 2009 Scopus update. The update involves the inclusion of new titles not covered before as well as the extension of coverage of publications which are not fully indexed. As a result, the values of the indicators throughout the website have been recalculated and the embeddings have been reconstructed to accommodate the new data. We describe below some important facts about the update.

Full Coverage of 2007 Collection
This update involves the processing of full publication and citation data belonging to Scopus 2007 Collection. Former data shown did not cover the last period of 2007, which has now been completed. Consequently, from now on, 2007 Indicators will only suffer slight variations, that if happen will be due to retrospective indexing.

Inclusion of 111 New Titles
New journals, in a number of 111, have been included into the database, going beyond 16000 journals covered. The full Scopus Collection has been incorporated to SJR, including even those journals presenting low coverage ratios, in order to minimize the time frame needed to display journal outcomes.

SJR Indicators recalculated
SJR indicators have been recalculated to accommodate all the bibliometric information provided by these new data. Last years indicators will show the highest variations since they represent the core of the update, however previous year's values can also experiment changes that will be more accentuated in some areas due to citation profiles.

Retrospective Data Inclusion
To increase the coverage of titles not yet fully indexed, retrospective data have been included. This set of data is usually formed by backward coverage expansion of partially covered journals which were incorporated to the database in recent updates as well as data corrections made as result of the data quality control procedure. However these data do not generally involve significant variations in the value of the indicators.
