"附说明的资料目录" can be translated into English as "Catalog of Materials with Explanatory Notes" or "Annotated Catalog of Materials".
Here, "catalog" refers to a list or inventory of items, "materials" denotes the documents or resources being listed, and "with explanatory notes" or "annotated" indicates that the catalog includes additional explanations or annotations for each item. Both translations are acceptable, and the choice between them may depend on the specific context or preference.
