Dynamic contextual library

One or more non-transitory computer-readable media storing instructions that are operable, when executed by one or more computing devices, to cause the one or more computing devices to perform operations comprising:

• providing, by the one or more computing devices, an interactive element for display in a user interface of a web browser running on the one or more computing devices;
• generating, by one or more computing devices, context data that indicates a context of the one or more computing devices, the context data indicating a uniform resource locator (URL) for a resource displayed in the web browser;
• obtaining, by one or more computing devices, document data indicating a subset of documents from a document collection associated with a user of the one or more computing devices, the subset of documents being selected from the document collection based on the URL indicated by the context data, wherein a first document is included in the subset based on (i) a stored mapping of the first document to a particular Internet domain, wherein the stored mapping designates the first document to be recommended when any of multiple resources in the particular Internet domain are displayed, and (ii) a determination that the resource displayed in the web browser is a web page in the particular Internet domain;
• after obtaining the data indicating the subset of documents and before displaying identifying information for the subset of documents selected based on the URL, receiving, by one or more computing devices, data indicating user interaction with the interactive element;
• and
• in response to receiving the data indicating user interaction with the interactive element, providing, by one or more computing devices, data identifying the subset of documents for display.

A method comprising:

• providing, by one or more computing devices, an interactive element for display in a user interface of a web browser running on the one or more computing devices;
• generating, by one or more computing devices, context data that indicates a context of the one or more computing devices, the context data indicating a particular keyword occurring in a resource displayed in the web browser;
• obtaining, by one or more computing devices, document data indicating a subset of documents from a document collection associated with a user of the one or more computing devices, the subset of documents being selected from the document collection based on stored mappings between specific keywords and specific documents designated to correspond to the specific keywords, wherein the subset includes at least a first document selected based on (i) the context data indicating that the particular keyword occurs in the resource displayed in the web browser, and (ii) the stored mappings mapping the particular keyword to the first document;
• after obtaining the data indicating the subset of documents and before displaying identifying information for the subset of documents, receiving, by one or more computing devices, data indicating user interaction with the interactive element;
• and
• in response to receiving the data indicating user interaction with the interactive element, providing, by one or more computing devices, data identifying the subset of documents for display.
