Final answer:
A letter-supplement refers to additional materials such as resumes, writing samples, or portfolios that provide further information about a candidate's qualifications. These should be appended thoughtfully, often with an explanation of their relevance, and serve to enhance the main application.
Step-by-step explanation:
In the context of job applications or academics, a letter-supplement or supplementary information may include materials such as a resume, writing samples, references, or portfolios. Often, these supplements provide additional evidence of a candidate's skills, experiences, and qualifications beyond what is covered in the main application or cover letter.
When including supplementary information, it is vital to attach a memo explaining the relevance of the materials and what additional insights they provide. An appendix may also serve as a section in a document where supplementary material is collected, usually related but not essential to the main text. Enclosures, such as reports or certificates, should be listed at the end of the correspondence under the word 'Enclosures' to inform the recipient of their inclusion.
Regardless of the format, supplementary materials should not be thought of as 'extra' but as integral components of your application that enhance and extend the understanding of your profile. It is, however, essential to use these materials judiciously and ensure that each piece of supplemental material adds distinct value to your application or submission.
