Concept: AACR II main entry contains bibliographic details arranged in a systematic order. The order helps users identify and access the document properly.
Step 1: Begin with title and imprint.
Title and imprint provide the main bibliographic identity of the book.
\[
D = \text{Title and Imprint}
\]
Step 2: Place note section.
The note section gives extra information about the document.
\[
C = \text{Note}
\]
Step 3: Place ISBN.
ISBN provides the unique standard book number.
\[
E = \text{ISBN}
\]
Step 4: Place accession number.
Accession number is related to the library's own record of the book.
\[
A = \text{Accession Number}
\]
Step 5: Place tracing at the end.
Tracing indicates additional entries made in the catalogue.
\[
B = \text{Tracing}
\]
Therefore, the correct sequence is:
\[
D,\ C,\ E,\ A,\ B
\]
