To what degree, if at all, were public libraries, hotels, and other public buildings of New York City segregated or denied to black people in 1927?

Although segregation was predominant in the southern
states much of the same behaviors in regard to segregation took place in many cities and
towns in the north.  In most of the northern cities the “separate but equal” concept was
affected.  Blacks were not allowed to share a taxi with whites, the must use separate
entrances to most public and private buildings.  Most blacks were excluded from
restaurants and public libraries.  Many parks were barred to the black community and at
least one municipal zoo had separate visiting hours.

Famous
jazz clubs such as the Cotton Club were also segregated.  The rise of Harlem Renaissance
did provide some venues for the black community.  The Hotel Teresa, located in Harlem,
although most of its visitors were white it did allow for few black businessmen,
musicians, and athletes.
