Determining if a publication is current
IBM regularly updates its publications with new and changed information. When first
published, both hardcopy and BookManager softcopy versions of a publication are
usually in step. However, due to the time required to print and distribute hardcopy
books, the BookManager version is more likely to have had last-minute changes
made to it before publication.
Subsequent updates will probably be available in softcopy before they are available
in hardcopy. This means that at any time from the availability of a release, softcopy
versions should be regarded as the most up-to-date.
For CICS Transaction Server books, these softcopy updates appear regularly on the
Transaction Processing and Data Collection Kit
CD-ROM, SK2T-0730-xx. Each
reissue of the collection kit is indicated by an updated order number suffix (the -xx
part). For example, collection kit SK2T-0730-06 is more up-to-date than
SK2T-0730-05. The collection kit is also clearly dated on the cover.
Updates to the softcopy are clearly marked by revision codes (usually a “#”
character) to the left of the changes.
