In the Statement of Responsibility (245 |c): In AACR2, any part of the statement of responsibility that was not taken from the chief source of information had to be placed in brackets and the source given in a 500 note field. In RDA, you only need to use the brackets if the statement of responsibility is taken from someplace other than the resource itself. The preferred source for the statement of responsibility is the source of the title proper, but you can also get the information from elsewhere on the resource and still not have to put the statement in brackets or reference the source in a 500 note field.
If supplying a date of publication or production (264 |c): If the publication or production date is not clearly stated on the resource, you can ‘supply’ the date, if you’re sure of it, and put it in brackets.
When describing unnumbered pages in the 300 field: Do not use brackets when noting pagination. Instead, use the words “unnumbered pages”
When supplying series numeration not found on the resource (490 |v): Continue to put this information in brackets, just like in AACR2, and add a 500 note identifying the source.
