Split text file into multiple files

I am having large text file having 1000 abstracts with empty line in between each abstract . I want to split this file into 1000 text files. My file looks like 

16503654    Three-dimensional structure of neuropeptide k bound to dodecylphosphocholine micelles.      Neuropeptide K (NPK), an N-terminally extended form of neurokinin A (NKA), represents the most potent and longest lasting vasodepressor and cardiomodulatory tachykinin reported thus far.  

16504520    Computer-aided analysis of the interactions of glutamine synthetase with its inhibitors.        Mechanism of inhibition of glutamine synthetase (EC 6.3.1.2; GS) by phosphinothricin and its analogues was studied in some detail using molecular modeling methods.

You could always use the csplit command. This is a file splitter but based on a regex.

something along the lines of :

csplit -ks -f /tmp/files INPUTFILENAMEGOESHERE '/^$/'

It is untested and may need a little tweaking though.

Something like this:

awk 'NF{print > $1;close($1);}' file

This will create 1000 files with filename being the abstract number. This awk code writes the records to a file whose name is retrieved from the 1st field($1). This is only done only if the number of fields is more than 0(NF)

You can use split and set "NUMBER lines per output file" to 2. Each file would have one text line and one empty line.

split -l 2 file
