1. A computer-implemented method for identifying contact information for an author of content that is relevant to a topic of interest to a user, the method comprising: receiving, by one or more processors at a first computing system and from a second computing system that is distinct from the first computing system, an indication of a topic of interest to a user; accessing, from a computer memory storage system, multiple pieces of content; in response to receiving the indication of the topic of interest, comparing the indication of the topic of interest to the multiple pieces of content accessed from the computer memory storage system; based on results of comparing the indication of the topic of interest to the multiple pieces of content accessed from the computer memory storage system, identifying a piece of content as being relevant to the topic of interest, wherein identifying a piece of content as being relevant to the topic of interest includes: identifying a first piece of content as being relevant to the topic of interest, and identifying a second piece of content as being relevant to the topic of interest, the second piece of content being different from the first piece of content; in response to identifying the piece of content as being relevant to the topic of interest, identifying an identifier for an author of the piece of content identified as being relevant to the topic of interest, wherein identifying an identifier for an author of the piece of content identified as being relevant to the topic of interest includes: identifying a byline for the first piece of content, the byline for the first piece of content specifying an identifier for an author who authored the first piece of content and a first media outlet in which the first piece of content appeared, and identifying a byline for the second piece of content, the byline for the second piece of content specifying an identifier for an author who authored the second piece of content and a second media outlet in which the second piece of content appeared, the second media outlet being different from the first media outlet and the identifier for the author who authored the second piece of content being the same as the identifier for the author who authored the first piece of content; accessing, from the computer memory storage system, contact information for each of multiple authors including identifiers therefor; comparing the identifier for the author to the identifiers included in the accessed contact information; based on results of comparing the identifier for the author to the identifiers included in the accessed contact information, identifying contact information corresponding to the author from within the accessed contact information, wherein identifying contact information corresponding to the author from within the accessed contact information includes identifying contact information at the first media outlet corresponding to the author; and returning, to the second computing system, an indication of the identity of the author and at least some of the identified contact information corresponding to the author, wherein returning, to the second computing system, at least some of the identified contact information corresponding to the author includes returning, to the second computing system, at least some of the identified contact information at the first media outlet corresponding to the author.
