The service is part of a re-release by the Library of Congress of its Print & Photographs Online Catalog. It provides access to a rich image collection for incorporation into other applications. Applications can search the catalog by description term, and if desired within particular collections, for specific image types, etc. Results can include just descriptive metadata or the images themselves, presented as a list, grid, slideshow, or gallery.
API methods support specification of a search query, either across the entire collection or restricted to certain elements, along with optional filtering criteria like subject and format. Methods also enable structuring of results and retrieval of related items.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
