What does the abbreviation LHM stand for in official documentation?

The abbreviation LHM stands for Letterhead Memorandum. In the context of official documentation, a Letterhead Memorandum is used to convey information, directives, or policy guidance in a formal and official manner, often bearing the official letterhead of the organization. This format lends credibility to the communication and makes it suitable for internal and external correspondence.

Other potential choices, while plausible, do not align with the common use of LHM in official contexts. For example, a Letter of Intent typically refers to a document expressing an intention to enter into a contract or agreement, which is different from a memorandum. Legal Help Memo might suggest a document specifically tailored to legal guidance, but it does not reflect the standardized use of LHM. Lastly, a Local Help Manual suggests a resource for community assistance, and although helpful, it is not recognized as LHM in the context of official memoranda.
