My understanding of the last sentence of 6.27.1.1 is that the instructions given under 6.27.3 are applied only "for new expressions of an existing work" (not for the first expression), i.e. the instructions relate to distinguishing these new expressions from the first one.

We are trying to establish the form of the preferred access point for the first (& only) expression of a work. We realize that the use of identifiers rather than preferred access points to link manifestations and expressions would avoid this issue, but we would still like to see if we can understand the requirements and would appreciate any pointers anyone can give. For a textual work with a single author the preferred access point for the work following 6.27.1.2 would be the author + title (preferred forms of each) eg Johnston, Alexa. Ladies a plate. Looking at rule 6.27.3 it seems that the preferred access point for the expression would be Johnston, Alexa. Ladies a plate. Text. Note that our resource is the first manifestation of the only expression of this work. There are no examples in the draft that show this kind of construction and all the examples cover the situation where more than one expression already exists. As around 70% of the titles we encounter are likely to have only 1 expression we are keen to know whether we have actually reached the right conclusion about expression access points. We looked briefly at dvds and it appeared that in order to create a preferred access point for a first expression we would be adding "two-dimensional moving image" to the title. A bit clunky! Then (we didn't quit while we were ahead!) we went back to rule 6.13 to look for distinguishing characteristics of expression and found examples using the film Blade Runner which showed the use of the terms "Final cut" and "Directors cut" for revised versions of the film, but again nothing for the original version. Is there something we're missing? Chris Todd & Charlotte Stretton National Library of New Zealand
