Because the British Library allocate different ISSN numbers to printed documents and documents that are available online, the Technical Report Series has two numbers:
ISSN 1361 - 6153 for the printed version
ISSN 1361 - 6161 for the online version and its printouts
ISSN 1363 - 8378 for the CD ROM version.
You can use any of these numbers when referring to reports from the Technical Report Series.
