Associating works with unique identifiers

A system comprising:

• memory;
• a communications interface coupled to the memory, the communications interface configured to receive information associated with a work;
• a processor operably coupled to the communications interface and to the memory, the processor configured to:
• access a database comprising a plurality of first identifiers, each of the plurality of first identifiers uniquely associated with one of a plurality of specific works;
• perform a first search to determine if the information includes a second identifier matching one of the plurality of first identifiers;
• generate a first match indicator in response to the first search yielding a match;
• perform a second search in response to the first search failing to yield a match, the second search determining if the information includes a first attribute of the work matching a second attribute of one of the plurality of specific works;
• and
• generate a second match indicator in response to the second search yielding a match.

A computer readable medium tangibly embodying a program of computer executable instructions configured to be stored in a memory and executed by a processor, the program of instructions comprising:

• at least one instruction to receive information associated with a work;
• at least one instruction to access a database comprising a plurality of first identifiers, each of the plurality of first identifiers uniquely associated with one of a plurality of specific works;
• at least one instruction to perform a first search to determine if the information includes a second identifier matching one of the plurality of first identifiers;
• at least one instruction to generating a first match indicator in response to the first search yielding a match;
• and
• at least one instruction to perform a second search in response to the first match indicator, the second search determining if the information includes a first attribute of the work matching a second attribute of one of the plurality of specific works;
• and
• at least one instruction to generate a second match indicator in response to the second search yielding a match.
