Upcoming Release of EFetch version 2.0

In November 2011 NCBI plans to release version 2.0 of EFetch. The major changes and updates are as follows:

*         EFetch now supports the following databases: biosample, biosystems and sra

*         EFetch now has defined default values for &retmode and &rettype for all supported databases (please see Table 1<http://www.ncbi.nlm.nih.gov/books/NBK25499/table/chapter4.chapter4_table1/?report=objectonly> for all supported values of these parameters)

*         EFetch no longer supports &retmode=html; requests containing &retmode=html will return data using the default &retmode value for the specified database (&db)

*         EFetch requests including &rettype=docsum will return XML data equivalent to ESummary output
Details about EFetch can be found at http://www.ncbi.nlm.nih.gov/books/NBK25499/#chapter4.EFetch

An updated, complete listing of supported &rettype and &retmode values can be found at http://www.ncbi.nlm.nih.gov/books/NBK25499/table/chapter4.chapter4_table1/?report=objectonly
