What is meant by "access"?

    Each of the following aspects constitutes a type of barrier to meaningful access.
    0. Existence / creation / preservation. Documents and objects need to exist in the first place.
    1. Identification. A suitable source needs to be identified. This "indicative" access is the realm of bibliography, documentation, classification, and indexing, -- of information retrieval.
    2. Availability. One needs physical access to whatever it is. Logistics and technology.
    3. Price to The User. The effort and expense of getting at or to something.
    4. Cost to The Provider. The effort and expense of providing access.
    5. Cognitive Access. Is the document understood? Explanation. Education.
    6. Acceptability. Credible? Acceptable?
